Anybody who's like "why are you asking for congrats?! dude, you're so selfish" is probably stung by their lack of competence to ask someone out, and they are probably older than the OP too. or they could be offended by the term "man-pants" which is fair enough, as it is a very silly term.

What good is a girlfriend when you're in high school?
it helps you mature. or at least i know its certainly helped me make better choices with my later on relationships. The odds of your first relationship being the person you stay with for life is actually whats slim.
I'm a guy, maybe some girls are naturally mature and know exactly what to look for/how to act (wouldn't suprise me, girls seem to be so much better at this sort of stuff than guys)... but for every single guy i've seen, from ages 13-28 (and by 20+ i usually expect people to be more mature), when they get a first girlfriend, they act like a twonk. They are either all over her, never speaking to her because he's just kissing/hugging her all the time. Or he barely touches her and only talks to her when he's trying to make himself look better than the other males around him. So you've got a relationship that won't work out in the long run because there is no communication("what!? you're a vegetarian? i can't commit myself to this!" "well yeah, if you'd have let me tell you...") or the relationship is just embarressingly bad.
had a girlfriend in high-school for just over a year. the first 2 weeks of that we barely talked... it was at that point i realised that i wasn't actually enjoying the relationship we shared, i was just having a bit of fun and 1-upping my friends ("hey look guys, i have a girl!")... after that, i was the other way round, barely hugging her, never kissing her and mostly talking. That was nice too, but she started to feel unloved within a week. It was then that i started to work the balance right for both of us and we were able to sustain it for about a year, until we both decided that we'd had a good run, but it was time to move on.
I think people should have at least 1 relationship before they are in University/College or job-hunting. it would mean a lot less morons who don't know how to handle one running around. But hey, thats just my opinion. Obviously i agree with you that a highschool relationship probably won't work out in the end, but its a learning experience that is definately worth having. rather be a douche at the age of 15 then get told i am one when i am 28!
anyway, rant over, wow did i go overboard... all i said is just opinion at the end of the day though, i am no doubt generalising and missing some facts, so if i get responses, don't be sounding angry and sweary
Anyway, Congrats to the Original poster, which i'd have done even without the suggestion. I thankyou for making a thread to encourage people to be brave and ask a girl out, rather than one saying "DON'T DO IT PEOPLE, IT WILL END UP IN RUINS AND TEARS!" like i feel some of the poeple in this thread are attempting. It can be hard to ask out a girl. I knew a guy (at highschool, huh

) who jumped out of a second story window in order to escape asking out a girl... we'd set it up for her to come in and he could ask her when we left the room... when we told him why we'd brought him to the room, he jumped out of the window. I'd say thats pretty brave/stupid thing to do, its just he considered that he needed more bravery/stupidity to ask out that girl xD.
PS

to be fair, you didn't say "congratulate me everyone!" you said "if you did, i'd appreciate it and thankyou for it").
