I'm a kegeling mothafucka. For about 6 months, every time I piss I do kegels at least 10 times to stop the flow of urine. Sometimes I'll do a couple of hundred (once every few weeks) until the muscles are to exhaustion.
Right as you're about to cum it's AWESOME being able to clamp down and kegel that shit from coming out, and it really changes up the sensations of my orgasms. Sometimes I will kegel before cumming, sometimes I won't and sometimes I'll kegel, then stop, then kegel and then stop again in rapid succession as I am about to blow and haha those are the ones where I have had comments from two different women about my forceful ejaculations/amount of semen.
ALL HAIL THE KEGEL.
