Is this an orgasm, or what..?

you can have them without being touched or even while waking up

I should have clarified, you don't need internal stimulation to have internal orgasms.

It happens anyway. Don't complain! Just go with it :-) this could mean that when you do finally have sex, you may explode from the feel good sensation. But don't worry, you'll still be in one piece, perhaps partially paralized temporarily, but that's a good thing
