13 Yr Old Nude Model
Clarence Pariseau
I am a male who experiences a lot of spontaneous erection. It's almost comical. My problem is that I model nude for art classes and have difficulty preventing or getting rid of my erection. The whole thinking about something else idea never works for me. I was wondering if you could tell me of a cream or something I could use to prevent an erection or possibly make an erection go away. I've tried the usual muscle and arthritis creams, but those don't work. I can still get an erection anyway. Is there something that numbs for a period of a few hours that I could use? I thought of using some desensitizing creams you can find at adult stores, but didn't bother trying them because I figured they're designed to help you keep your erection, not lose it. It would be very helpful if you could help me out.
It sounds like you're a pretty upstanding model. Maybe the "joy" you experience while modeling stems from the pleasure you feel when others focus on your nakedness. Or as you said, your stiffness may be completely random, occurring for no rhyme or reason. Spontaneous erections are one of nature's happy mysteries, and there's no cream or pill to get rid of them. However, there are some other options to prevent an "at attention" scene while you're on the job.
If your erection continues to pop up without an invitation, have you considered finding another job that's better suited to your skills? For example, if you want to continue modeling, you could find a more penis-friendly studio or magazine that's into erotic art. Or, you could look into more traditional modeling gigs where the focus is on fashion, not your form.

Finding models used to be fairly easy, but now I seem to be competing with OF and girls selling direct. Good for them all, bummer for me. I offer $500 to $1000 per four hour shoot, depending on posing, location, my paying travel expenses for her, etc. I offer to provide some of the photos for their OF content, and can cross promote from my site to her OF page. I see it as a mutually beneficial relationship, but I can only see it from my side.
I've been on MM for years too, but the models there willing to do anything beyond "art nudes" or "implied" (which, if we were all honest, seems to be just more respectable terms for what I am doing) seem to be scarce.
Diabetes is induced in mice by using streptozotocin (STZ), a compound that has a preferential toxicity toward pancreatic β cells. We evaluated nude male mice from various sources for their sensitivity to a single high dose (160 to 240 mg/kg) of STZ. Diabetes was induced in male mice (age: median, 12 wk; interquartile range, 11 to 14 wk; body weight, about 30 g) from Taconic Farms (TAC), Jackson Laboratories (JAX), and Charles River Laboratories (CRL). Mice were monitored for 30 d for adverse side effects, blood glucose, and insulin requirements. In CRL mice given 240 mg/kg STZ, more than 95% developed diabetes within 4 to 5 d, and loss of body weight was relatively low (mean, 0.4 g). In comparison, both TAC and JAX mice were more sensitive to STZ, as evidenced by faster development of diabetes (even at a lower STZ dose), greater need for insulin after STZ, greater body weight loss (mean: TAC, 3.5 g; JAX, 3.7 g), and greater mortality. We recommend conducting exploratory safety assessments when selecting a nude mouse source, with the aim of limiting morbidity and mortality to less than 10%.
CT image of the orthotopic xenograft of lung cancer in nude mice. Figure A shows small right lung nodules one week after intrathoracic injection of tumor cell suspension and Figure B shows gradual growth of intrathoracic nodules; Figure C shows right lung mass markedly enlarged for several times.
In this study, spiral CT was also adopted to perform real-time evaluation of tumor formation following intrathoracic inoculation of nude mice, showing solid tumor formation in right chest of mice at around one week following injection of tumor cell suspension. The trend of body weight changes in tumor-bearing nude mice in Figure 1 reflected a declining trend of mean body weight of tumor-bearing nude mice at around 10 days after inoculation of tumor cells and the time point for body weight decline of tumor-bearing nude mice was basically consistent with the emergence time of tumor formation indicated in CT results. Thus, in this model, it is critical to observe body weight changes in nude mice following orthotopic injection of tumor cells to judge the successfulness of tumor formation. Gross anatomy and pathological detection of nude mice successfully established with an orthotopic lung cancer model confirmed metastatic foci in contralateral lung tissue, mediastinal tissue and chest wall to varying degrees, with an intrathoracic tumor metastasis rate of 100%, consistent to other similar reports (2,13). This may not only be related to characteristics of tumor cell metastasis and invasion, but also be related to the short survival time of nude mice following tumor formation and short observation time.
In the preliminary experiment of this study, two nude mice rapidly died of intrathoracic massive hemorrhage and respiratory tract symptoms of hemoptysis after withdrawal of the puncture needle. This can mainly be explained as follows: the point of puncture was located besides the posterior axillary line of the sixth intercostal space of right chest wall, which was close to the hilar vessels after insertion of the needle and could pierce into hilar vessels to induce intrathoracic massive hemorrhage and rapid death, as also confirmed by subsequent gross anatomy. In order to avoid injury to hilar vessels, the location adjacent to the median or anterior axillary line of the sixth intercostal space was chosen as the point of puncture and the depth of needle insertion was strictly controlled at around 5 mm. The subsequent puncture process was successful without occurrence of aforementioned phenomena.
The orthotopic animal model of lung cancer can well mimic the real environment of tumor growth, but due to tumor location within the chest, it is not conducive to real-time observation of the implanted tumor mass in the experimental process. In some orthotopic lung cancer model studies, pathological anatomy is performed after execution of a certain number of nude mice regularly or at the end point of observation to monitor tumor growth and dissemination, but this method requires a big number of nude mice and a great deal of time or energy (12,13). In this experiment, spiral CT scan was employed to conduct dynamic observation of intrapulmonary tumor growth within mice, which can not only clearly observe the successfulness of intrathoracic tumor implantation, but also observe the gradual tumor growth in vivo over time, to judge the occurrence of mediastinal tumor metastasis. Some studies also put forward using micro-MRI to assess the lung tumor model in small animals (14), but some scholars have pointed out that among lung tumor images, compared to micro-MRI, micro-CT behaves better in contrast imaging of air and soft tissue (15), so more studies apply micro-CT to observe the lung cancer model of rodents (15-17). Indeed, micro-CT is superior to conventional spiral CT in resolution of in vivo imaging of small animals, but micro-CT equipment is not liable to be obtained for many research units and ordinary spiral CT can achieve the slice thickness of 1mm, which can observe orthotopic intrathoracic tumor growth and development of nude mice. Thus, as an objective and feasible method, dynamic spiral CT scanning can be further used for efficacy observation during antitumor drug experiments.
A physiologically based pharmacokinetic model to describe the biodistribution of a specific monoclonal antibody IgG1 (ZCE025) and its fragments (F(ab')2 and Fab) and of a nonspecific IgG1 (MOPC21) in normal tissues and a human colon carcinoma xenograft (T380) in nude mice is developed. The model simulates the experimental data on the concentration of these four macromolecules in plasma, urine, heart, lung, liver, kidney, spleen, bone, muscle, skin, GI tract, and tumor. This is the first such model for macromolecules with specific binding. A two-pore formalism for transcapillary solute exchange is used which avoids the oversimplifications of unidirectional transport or a single effective permeability coefficient. Comparison of the model with our biodistribution data shows that: (a) a physiologically based pharmacokinetic model for specific and nonspecific antibodies is able to explain experimental data using as few adjustable parameters as possible; (b) for antibodies and fragments, the tumor itself has no significant influence on the pharmacokinetics in normal tissues; and (c) the two-pore formalism for transcapillary exchange describes the data better than a single-pore model without introducing extra adjustable parameters. Sensitivity analysis shows that the lymph flow rate and transvascular fluid recirculation rate are important parameters for the uptake of antibodies, while for the retention of specific antibodies, extravascular binding is the key parameter. A single-pore model could also obtain a good fit between model and data by adjusting two parameters; however, the estimated permeability was 1000 times higher than with the two-pore model, and the binding affinity was such that approximately five times more material was bound than free in the extravascular space for nonspecific antibody. Setting the binding affinity to zero or reducing the value of the permeability-surface area product did not allow a good fit, even when the lymph flow rate was varied. The present model may be useful in scaling up antibody pharmacokinetics from mouse to man.
