I can relate to you in not remembering some parts of sex. I couldn`t remember if some guy ejaculated in me, so I talked to him after(maybe you should do that) and he said he don`t remember either, And I just forgot about it, and I don`t care.
But if you are so concerned all the time, and has difficulty concentrating on anything else, I guess it might be a sing of OCD. Search more symptoms and see if you can relate to them. But it doesn`t have to be.
I guess when you are horny or concentrating on rejecting, it`s possible not to pay attention too much on everything, and then not recall everything, I think you should relax a bit.
The best advise I have for you is to visit an expert, psychiatrist. Only he can tell you whether you have or don`t have problem.
Best wishes...
Good point mayb I was to busy rejecting her, that I didnt put much attention to everything that had happened. I did ask her again if I penetrated her. she said "no" we didn't have sex because I was pushing her away. She even added that not a small part of my penis entered her. But somehow I am not sure if could rely on her answer. I believe at that time she had too much to drink.
I keep putting in my mind that to my knowledge there was no penetration. And she did confirm that nothing happens yet I still am not convince and it's driving me crazy.
Maybe she did drink and it`s normal not to believe in what drunk person has said. but, on the other hand, i think this should`t bother you so much.
this situation is just a segment of your whole story and the most of us here arn`t experts, so the best thing you can do is to visit psychiatrist. Your behavior might be OCD, or some anxiety disorder, or something else. But it`s important that you solve it because it will bother you, and you live only once so don`t let this situation to ruin beauty of your day.
