What's happening during Anal Play?
 

I posted this on the general lounge page before noticing an advice link, so I'm posting it again here...

So this thing happens whenever I play around with my Butt Plug (in my butt of course). Basically, whenever I start pumping really fast and hard, my abs kind of contract and a LOT of precum comes out, almost like I'm just peeing, except it's not pee. It only lasts for a few seconds, and it feels pretty good. It is also possible to do this repeatedly, too, which makes me think it's not some sort of anal orgasm. I'm guessing it has something to do with my prostate getting really stimulated or something. Does anyone know what this bodily function IS?

Sounds like a prostate orgasm, though that's more a guess than actual knowledge

but I didn't ejaculate sperm until I actually started jacking off. it was just precum...

Prostrate orgasm is basically like a lot of pre-cum. I have had a prostrate orgasm a couple of times and each time it looks more like pre-cum,but is a lot more of it and it feels awesome to have happen and you can do it multiple times in one session. The hard part for me is not making myself cum before I am done milking the prostrate. I normally get so horny miling my prostrate that I grab my cock while thrusting my ass and blow a hell of a load.

I learned in Human Sexuality class that the male prostate has the same developmental root as the female gspot (there are fancy words that go in that sentence that I don't remember, hopefully it makes sense anyway), meaning it is possible to have a different sort of orgasm from your prostate. Obviously, being a female, I can not tell you if that is what you had, but I have had many gspot orgasms and they are much different than the clit ones for sure!

What do you mean "done milking the prostate?" Is there a point at which no more precum comes out? or is there a point at which actual cum comes out?
