Here's another little piece of advice from me: cherish the people who don't care that you've been an absolute failure at romance/sex, because honestly, there is so much more to life than that.
Never underestimate the power of having a really good friend who will give you a big hug when you're feeling like crap and who will always be by your side no matter what. Sure, dating someone is nice, but having that one special friend to talk to can be a lifesaver.
