Here's an an abstract from an article about physical and sexual
health. I'm not sure if this will interfer w/the group that is assign
sexual health.

Sexuality is a major way of intimacy in human being and it is very
important in gender relationship, contributing to over all health.
However, since association between sexual activity and sudden death
determined by forensic autopsies related to cardiac or cerebral causes
has been reported, some people with heart disease often abstain from
sexual activity that could affect the quality of life. It is therefore
important to learn the physical demand of sexual activity and the risk
it may trigger. For decades, the cardiologists have conducted
observational studies and clinical trials on healthy volunteers or
patients. The most common indices responding to cardiovascular risks
of sexuality were variances of blood pressure (BP) and heart rate
(HR), monitored by ambulatory blood pressure and dynamic
electrocardiogram recording. BP and HR increase during the coitus just
briefly and quickly recover to baseline level. Peak coital BP occurred
at onset of plateau phase and quickly decreased, instead of emerged at
orgasm as most people supposed. The metabolic equivalent of energy
expenditure during the orgasm was relatively modest when compared with
other physical exertion such as cycling. Epidemiological studies have
suggested that sexual activity has favorable effect on health in the
long term. This review summarizes and discusses the advances in the
researches dealing with cardiovascular effects of sexual activity to
better inform the cardiac patients.
