Whoah.. the males are actually debating from their points of view...

Well, 18 and no boyfriend is nothing... Having a boyfriend doesn't even complete your life if he is a jerk/ *******/ gambler/ abuser. Why knowing him may even cause your downfall so bad you may be even traumatized.

You are just envying and jealous of your current girlfriends having boyfriends. Surely you have other circle of friends... they can get all cutesy with their boyfriend and ditch their girlfriends alright, and if they ever break up, tell them not to find you (cause they likely will, like i said, likely and not complete). All in all, you're just feeling a little love sick. You get exposed to sudden romance taking places around you but you're the only one who didn't have. If it's really unbearable, just talk to your father (laugh), he is a good man alright(if not your mom won't have married him in the first place).
