Wow Lilith, you could have almost wrote my post for me

I also sometimes feel...not really envy...but something similar, towards my single friends who are living on their own, doing the "adult dating" thing, etc, I was married at just-turned-20 to my high school sweetheart. To add to that, I've never had sex with anyone but my husband. But, I also wouldn't trade what I have now for all the experience in the world

There's no rule that says you have to be in a committed relationship/ married/ have kids by a certain age. Don't allow what others have done to dictate what's best for your life, right now!
