"I'm almost 15. Anyway, why would I want to wait till I'm close to 30 for a long-term relationship? I want to have one as soon as possible. Now, I've never had sex nor have I had a girlfriend, but from what I imagine, a long-term relationship would be much more fun and fulfilling than just sex. Am I just being naive? Are relationships really not as fun as I imagine them? If so, why would people have them at all, then?"
The adult wiring in your brain obviously hasn't connected up yet. When it does you'll be driven to spread your genes as far and as wide as you can. That's the basic male drive. Wait a year and you'll probably want to lose your virginity as soon as possible. I know I did; but back there and back then (40-odd years ago) the girls got their attitude towards sex from their mothers and their mothers hadn't had the benefit of The Pill, so their attitudes were very conservative. You had to date a girl for *months* before you got more than a kiss. Only a "slag" would sleep with a guy earlier than that. These days the girls still get their attitude towards sex from their mothers, but their mothers had the pill available to them and so did their mothers... Times change. Attitudes change. Morals change. Society changes. When you're good and ready go out and enjoy yourself. Butterfly. Learn. Your friends will. The girl you fancy and want a long term relationship with will (and that'll break your heart). It'll hurt, but you'll survive, you'll get stronger, you'll get smarter, you'll learn, we all do. When you're older don't be afraid to get out there and live a little.
