The squirting thing
Well even the doctors can't agree on this highly controversial issue (lol) so I'll only give my own experience and maybe others will add to it.
It's not a case of having a "dry" vs "wet" orgasm, it's internal and external - both are wet! If you've ever had say 3 or more fingers inside a woman when she has an orgasm, you've felt the shock waves that happen inside, everything pulses and there's a gush of fluid but all inside. The squirting happens when, it's kind've like catching one of those shock waves, and I push it, (it actually feels like I'm pushing it "outside",) and then I get this really intense feeling that just explodes on the outside.
The cool thing is, after a while you can get control over the whole thing, (do those kegels ladies!) and have one or the other or both at the same time, and after the first or second orgasm, those external squirting ones, you can make them happen with very little stimulation.
You can go overboard too though - a while ago I guess I pushed too hard or too often and over stimulated those muscles to the point where it felt like I was having an orgasm every time I peed (which uses the same muscles). It sounds great, and I'm not really complaining, but it was a bit distracting sometimes, especially in public bathrooms.
