I've very very inexperienced when it comes to receiving anal stimulation. My BF seems happy to be the btm, but I felt I should make myself available. I decided one afternoon to give it a try... I was incredibly relaxed, I was practicing with fingers... and when the time came... it felt awful, a combination of pressure and having to go to the bathroom really, really badly... I wasn't gripping or tense... but I wasn't getting anything out of it... I lost my erection, then my BF started to lose his interest in the situation... He decided it wasn't working, so I flipped him and went at it like usual... But I've been reading that there are guys who just aren't responsive in that way?? Thoughts? Experiences?
