I am a gay man who lives alone, so I don't have the problem so do.
However, I was married before coming out and have three adult
children. I have a wonderful open relationship with all of them, but
I have not shared my love of diapers with them. I guess because I
don't see the need to, but if they were to discover my diapers and
plastic pants I would have to address it. My sense is that we could
talk about it and it would be ok even if they thought it strange. So,
having said all of that, I realize it is not the same situation as
someone who has a spouse/mate who doesn't know.
I think it all depends upon the quality of each individual
relationship. I know I could not have shared with my ex-wife because
she has a way of applying her own idea of what is "right" and this
would not be part of it. She would not have been open to trying to
understand. If that is how the relationship is, then sadly one must
continue to hide.
I don't feel guilty or perverted nor do I think anyone should feel
that way, but the openness and ability for good conversation between
two people will dictate how they should proceed.
All of this rambling is probably not very helpful, but they are my
thoughts at the moment to Terry's questions.
