Well, I'll say it takes guts to write about something like this, but it can feel liberating. Until about 6 months ago, I was never comfortable talking about sex (this might have to do with my inexperience,) but after meeting ST, and sharing some of my deep dark fantasies with her, and being accepted, it's gotten easier. So congratulations on dropping that inhibition.
And each person is different when it comes to having an orgasm, but I'd doubt you'd be able to find someone who didn't move around at least a little.
