I am kind of depressive guy and i have idea is that sex is not the answer since i am chubby guy and not feel attractive about myself and think that is more disgusting to the other person, no matter how good or whatever is. So i like doing ordinary stuff with this girl. And she asked to come to her home to just sleep over since it was too late and in far distance from my home. So i didn't think anything sexual. When i get there she became frisky and started initiating things. So i did not tell no directly since i did not want that she would be hurt by rejection. However, i showed her clear signals that i am not participating. Then she'd become rapey, and i pinned down her hands and her to the bed trying to constrain her but she got even more aroused because i guess she felt dominated, as i was 'anticipating' that it is pleasuring her. However, nothing happened, i've left her alone and felt guilty for leaving her unpleased...
