I have a friend who apparently just had his first relationship and he's 26. I'm not sure how accurate that information is, but it doesn't exactly surprise me. I wouldn't stress too much about being 17 and without a relationship up till this point, you've still got time before it gets sad. Also, if you're in high school I don't recommend a relationship in your last year. It fucked mine up when she broke up with me 2 weeks before my final exams. Not cool.
diana -- Its awful to constantly see all those silly happy couples together, especially when the only people you have to bitch about how lonely you are, are them. I always feel guilty if I mention how lonely I am to one of them, because it seems like they suddenly feel guilty for being happy, and I don't want that.
Darknesslover -- Like I said before, if you're pissed at losing some freedoms with your girlfriend, its not worth you staying with her. You have to take the good with the bad for a relationship to work. If she's getting super clingy, it might be unhealthy, but I don't know so I won't comment further on that. Just don't come in here and whine about how much being with someone bothers you, as many of us would almost do anything for that kind of companionship. And thanks for your apology before.
