There are lots of different variations on a theme here. Some women on this planet will only ever experience one sort of orgasm, which is usually the clitoral orgasm. Therefore, in their opinion, an orgasm is an orgasm.
However, you can have the following:-
- clitoral orgasm
- vaginal orgasm
- ejaculation (without orgasm or muscular spasms)
- ejaculation (with muscular spasms_
- all of the above
Supposedly all us girls can achieve everything on that list if we practice. Personally, I've only ever discovered two of these.... Doesn't stop me practicing though!! ;o)
