When I was exercising and doin other things such as the ol' kegel I was able to last up to arond an hour on a good day.. But it got a bit to much for my girl.. I can get up to aruond 300 'squeezes' I guess is what happens with the PC muscle.. I think that I read somewhere that a normal healthy PC muscle should be able to do 300
Reading the experiences of the girls.. wow.. looks like i'll have to get my girl onto them.. hehe
