Had a circumcision as it would take me ages to cum. Often, to great embarrassment, not at all with someone new. Urologist said it would help as foreskin was tight. Initially head was super sensitive after the operation. Three years later not so much. Didn't really resolve the problem either. Its obviously a mental issue rather than physical. Sometimes not a problem and can shoot for England. Other times no matter how hard I try or want to, nothing happens. Probably wank too much as well which doesn't help. On the positive side, cock does look much better. Helps that it's a big one though...
