I have ones like you too, jasper. it's funny because i can have them pretty easily but they really don't feel all that fantastic and it is more the clitoral orgasms i crave. anyway, like you, when i have them a LOT of fluid comes out and i end up putting a towel down on the bed just to sleep. i have to wash the sheets a lot which IS a pain, but my boyfriend really likes it when i have these types of orgasms, so i guess i don't mind too much. what bothers me is he thinks that just because all that fluid comes out it MUST mean it feels really amazing for me, but it doesn't. for some reason, i just ejaculate alot.
the first time it happened i thought i peed on the guy too! but now i know what's going on. if you feel comfortable with it and your partner seems to, then by all means, enjoy! i have found that most of the men i have been with are totally turned on by it. now, if only i could be too...
