I'm almost 21 and have v*'d on two occasions; when I was 10 I v*'d about 5 or 6 times and then when I was 16 I v*'d while extremely drunk (which I only have a vague memory of doing). I think the worst part is definately the lead up to it, the nausea which can be awful. The actual v* itself doesn't last a long time and can make you feel a lot better once it's done.

I'm sure a lot of people haven't v*'d (or hardly) during their lives and you could easily go many years without it happening to you. I'm hoping I do! But yeah, as much as it terrifies me - the experience isn't AS bad as we all think it is.
