OP here: I've felt like this before, the regret. I've cheated on 2 of my girlfriend, probably doesn't really matter because I'm only twenty, I was only about 16 with one and 18 with the other. But after having sex with one of my best friends (which was a hot piece of spic ass too) I felt guilty. Not while having sex with her but afterwards, that shitty feeling you get after realizing you let your dick do the thinking.
Anyways, that's the feeling I have with my cousin now. More of a bad "morals" type of feeling. But like some of you said, fuck it. I'll bring it up next time I see her which will more than likely be this thanksgiving. I'll get her alone like the person above me said.
