I have a boyfriend. We do 'things' we haven't had SEX SEX yet because im waiting for my birth control to set in. but in my experience, I was really nervous and uneasy about him seeing my downstairs junk. We started off slow, and I trust him. and now, I actually like him touching me there.. it feels good, I still do get a little dysphoric about it, like, I dont really want him to look at it, and I dont like my pants all the way down. Stuff like that. But, he helps me feel better by calling me 'boy' and that sort of thing, and i keep my binder on, and he always calls them my moobs.
id say its all about trust, sure you WILL get dysphoric, dude, I bet even buck angel gets dysphoric sometimes. but if you trust the person, after a while you just learn to use what you have.
