just be careful sis, orgasm control conditioning, or what my owner calls "cum training" is a longer proccess than many people realize, it should be done slowly in small increments

the pain does sound like a pinched nerve caused from the sometimes violent spasms experienced during ,,, make sure yu stay plenty hydrated and limber, i reccomend tantric meditation and yoga for the mental and physical asspects of those that are attempting to achieve full orgasm control,

it can be a very wonderful and rewarding experience if done correctly if you ever need any help feel free to ask boo, ive been there, winks

hugs and kissess
