When I masturbate, I can think of anything under the sun and I'll still get off. It's kinda weird
But normally it's one powerful orgasm, then I have to take a few minutes to recooperate, then i'm ready for another big orgasm. As for sex, I can have a few small ones in a row, but normally I have one big one then i'm done. I get super dry after I orgasm too, so lube is a must if we're still going at it
