What I feel isn't like with a clit orgasm. It doesn't build up and then explode with goodness for 5-10 seconds before it stops and gets sensitive. It's a constant good feeling from the beginning, that also feels better the harder it is, and then after a few mins of feeling amazing, it starts to feel less and less good until I get to the point where I feel I'm gonna start hurting soon unless I stop.

Is that an orgasm from penetration?

Also what are multiple orgasms? Are they clitoral or vaginal or both? Are they one after another straight away, like an extra long orgasm? Or is it just that you can have a clit orgasm soon after the last? Is what I feel through penetration a multiple orgasm because it lasts so long?

I'm 28 and I feel like I should know this by now but I don't have female friends so I don't know.
