There was only one time where I almost lost consciousness. It was the weirdest thing, and I think it was because I was near orgasm... lol. But yeah, I stopped after that... it was very strange. But then again, I've also fainted in the past before... this was slightly different, and I didn't actually faint, but came close to it... lol. Except whenever I have fainted, I only faint long enough to hit the floor, and then I usually am conscious.
