Fucked a girl, now I feel like shit.

I had sex with her three times in three days and I had the same consequences just like when i fapped. Bad mood, super irritated by simple stuff, no energy, no mental clarity. I told her that if we are to continue i am not going to cum anymore at the end, but if i can't manage that i am probably going to end it. I ain't going back to my old self just to hump over another human being like an animal. I got greatness to catch up and she's waiting for no one.
