<human>: My boyfriend and I not long had sex but he never usually lasts long which is okay, we just do it a second time. We were trying new positions but he couldn't "get up". Now this situation happens a lot but today, I had no patience. I got my clothes on, told him that he should leave (he needed to go anyway) and gave him the cold shoulder. I don't know what it was, but something struck inside me and I just felt disappointed and I swear I'm feeling something else but I can't put my finger on it. I have done something like this before for the same reason, but not this bad. 

I crave sex, despite orgasming very rarely and not feeling much throughout. It was something I was never really interested in before, it was something I was usually forced into by my ex's, I rarely wanted it with them. I guess that was my purpose to them and I fear maybe that part of my past is coming through and making me crave sex, to feel validated/important almost. When I can't have sex with him, I don't know if I'm disappointed in him or myself or just impatient. I have no idea. 

When we can't have sex, part of me thinks back to my past, questioning why I want sex so much, another makes me feel like I'm not sexy enough for him so that's why he can't get up or I think he's not trying hard enough to try and find a way to improve both our sex lives. 

I want to apologise too and I usually do for such things but part of me feels like my bitchiness was validated. I only ever apologise if there's no reason behind it, but I feel like there is in this situation. He said he was really shocked and had seen another side to me which made me see how bad I was and he's probably going to feel shit about it. 

I'm hoping someone could give me some idea as to what's causing a problem here and how to resolve it.

Can you provide a brief overview of the text?
<bot>: Got angry at boyfriend when he couldn't perform and I'm not sure why. I'm pretty sure he feels terrible right now too.
