honestly it depends on person, not all intersex people orgasm in same way, some may do it with their clitoris or penis and some cases both when the pathways are merged. And when they pee I think they pee from both ends since also that pathway is merged, this is all i know from what I have searched information may not be accurate but i did my best to answer your question. I know it's genuine curiosity to know how stuff works but the way you asked was just rude yk and also this is fictional porn so I assume the author isn't serious about depicting the anatomy properly so no need to take it that seriously
He has a dick and vagina? Wth is that, whats the purpose of his dick?
