Plus it means you're 19 and thus can do lots of fun stuff 17-year-olds can't. Even if you do lose two years of your life.
Surely it would be more beneficial to ask when people lost their virginity? A 21-24 year-old could only just have lost their virginity, or it could have been when they were 13 so...
Sex is made out to be such a big deal. I know it's easy for me to say (female, 17, no) but it will happen when it happens. If you rush into it, you're likely to regret it afterwards. Similarly, if you build it up to be such a big deal then you'll end up becoming much more worried both before the time and when the time actually comes around. If you're relaxed about it then you'll do it when it's the right time for you, and when it does happen then it'll be much more enjoyable. I have no regrets about losing my virginity, but I know people who have, and I'd much rather be a 20-year-old virgin than not, but wishing I was.
