easily and often bro. to different degrees of course. congrats if you got one. i have one, but to a lesser degree. she cums at least once most of the time twice, which i think is about right.
Once tried the same on E. Fucked for almost an hour without cumming. Was frustrated so went to bedroom, watched some porn and waxed my pole for another hour before finally getting that damn money shot.
E is a fucking love-hate deal. You feel so great and sex is so good but it's damn near impossible to cum....
one time on crystal meth I jacked for so long it bled out the end. just a few smears of blood on my hand. then I knew to give it up. flogging a dead horse with that drug.
coming off acid was another 'no deal' issue. but I felt the need everytime to try to get ti to work. it became a challenge. unless I had a girl there, then I got her to do it.
