How do you know when the right girl comes?

Hi, I'm 14 years old. I haven't kissed or dated anyone, and although I try to be confident, optimistic, and cheerful, every girl flat out rejects me. I mean, I'm smart, I have Straight A's. I have friends. Sure I'm not Mr. Popular hut I have lots of great friends and am on good terms with pretty much very one I know, I don't have a single enemy and I have never been bullied. I'll admit I'm not very attractive, but is that really something that will set those other qualities back? I am extremely polite, that I am super strict about. I will always put myself last. I can NEVER ask for something without saying please and thanking the person, and I always out myself last (the way I see it, is society goes like this for me: the disabled, children, the elderly, women, and men last [and I'm a man]). I will always open the door for others and like to play sports, too. Yet every girl still just rejects me and I feel sad :( I've always dreamed of marrying a sweet, kind woman with virtues and intelligence (beauty would be nice, too, but that isn't as important). I would love to have kids, and a big family to shower with love. But somedays, i feel scared,like that's never going to happen. Generally, I am wealthy, so sometimes I wouldn't mind marrying a gold digger or a cheater just to have someone :(
