I am in a good shape, taking care of my health and fitness.

Banged this chick, which I haven't seen in a while and has apparently gained weight during this time. We fucked.

But after that day, I feel like that sex took my soul away. That I fucked a physically unattractive chick, which it would be better for me to masturbate instead.

And I've been pretty depressed after that. Meaning, my libido is kinda gone. Reverse rape?
