I'm a 20 year old woman in a relationship with a 19 year old guy, and one of my major fantasies is to anally penetrate him. When I first brought it up, he was interested because he knew I loved anal and he'd heard it felt really good for men. But then he tried to finger himself and it ended up immediately triggering diarrhea (sorry if this is tmi). Also, I like to touch and gently slap his ass, but he recently told me that he doesn't like it.
Whenever I bring up things like fingering him or rimming him, he tells me that he would be okay with it, but I'm starting to get uncomfortable. I still really want to penetrate him, but I'm wondering if he's just telling me that he wants to do it because I want to. Consent is really important to me so I don't want to make him do something he isn't into. Does this sound like a situation where I should back off?
Also, if it turns out that being penetrated really is something he's interested in, how can I make sure it's a good experience for him? I've always loved anal and it's always been relatively easy for me, so it's hard for me to understand where he's coming from. I'm especially worried about making sure that putting anything in his ass doesn't make him evacuate his bowels again. Thanks.
