I don't know what up there makes it feel so good. The female anatomy is elusive to everyone. I would say the g-spot IS the vaginal orgasm, but what are the chances that I happen to have a g-spot. One person can't be THAT lucky.
I thought every girl had a g-spot. It's that spongy part on the upper part of the inside wall. The female anatomy is not elusive to me. I know all about your Skene's gland, etc. That's where those that squirt squirt from. Can you find your g-spot right now? Give it a try and get back to us.
if you believe hipforums, there's also a nipple one. and i think i saw one thread about one that came from absolutely nowhere.
