So, the problem with everyone else you've dated is their lack of muscle, or is it they weren't constantly trying to max out their squat, bench, and DL?
their problem were that they got too comfortable. Like they were my sisters and I their Brother. Farting, shitting, gynecological crap... nothing was out of the ordinary. Wearing baggie/comfy clothes in the evening. Gaining 22 pounds in the process doesn't help either. I mean what am I, a black man from ugabuga jungle? A woman either takes it personally, or like "gets it", not understand it, but "get it" and underSTAND that the quality of mans erection has nothing to do with having pussy next to you 24/7 in whatever form possible.
As soon as you feel like you don't have to hold on "to this dime" it's down hill. You either survive and live it, work on it or you quit.
