...but when i was 19 and in my first LTR (i had had one boyfriend prior, but he wanted more commitment than i was ready for, so i bailed), there was occasionally a bit of a BDSM flavor to our sexual relationship. he really enjoyed watching me masturbate and verbally directing me while i did so... once he directed me to continue stimulating myself, even after my first orgasm, and i was able to have two in a row. that's the only time i've ever been able to do that. my refractory period is significant, and i usually get too sensitive after orgasm for any sort of clitoral stimulation for several minutes at least.
i envy anyone who can have an orgasm lasting more than a couple of minutes (i would say 30 seconds to a minute is average for me but 2 minutes is probably my maximum)! Caitlyn, i am totally jelly!
however, i have had something akin to what i would describe as an extended 'full body orgasm,' but without any clitoral stimulation. it's not an orgasm in the traditional sense. but someone with the right sense of touch, can stimulate my body in such a way that i can be held in ecstasy for an indeterminate length of time - sometimes hours. this, IMO, is even *better* than orgasm.
one time i was touched in this way until i was literally crying (primarily nipple stimulation - WOW are my nipples ever sensitive). i wasn't sad or upset in any way, just totally overwhelmed with pleasure. but the 'soft touch,' applied in just the way i like it, is a pretty rare gift. it also sort of requires a LOT of time and a lover who legitimately gets off on giving pleasure for pleasure's sake, not just to cause an orgasm.
