Good question. I know the feeling myself and I asked myself the exact same question. OK, I'm not an expert on love and all that it implies, but I will tell you some common sense tools. First and foremost, hygiene/cleanliness. My mom tells me all the time to wash and be clean (because, like most of us teens, our bodies smell the worst in our lives) so I can look decent. If you have the same problem, find a good anti-perspirant/deodorant or either one separately. Anti-perspirant means that it will fight and/or block any sweat (or perspiration, hence the name) that comes from the armpits. Deodorant basically takes away the odor. I suggest getting Sure, Mitchum or Degree due to the high level of Aluminum Zirconium Tetrachlorohydrex (which is the active ingredient in these products, encompassing around 15-20% of the product, which is what you need for the problem of body odor). Second, the age issue. You're 15 and the girl could be older (which is no problem unless she has some issues). Don't let age be a stumbler in any sort of date. Third, topics. I would suggest asking the girl what she wants to talk about. Women feel more respected when they are listened to (I know, most of my life and in my family are women). If she has nothing to say, then you bring up something. Fourth, how you should bring it up is to do it in a nice but respectful manner. Don't be too serious or too nervous; women can almost always sense this. Fifth, where you should go to is to a nice restaurant. First, before you go to any place, ask her what food she likes. If it matches your food preferences, then ok. If not, then at least you could try out something new. Don't EVER do two things: go to a place YOU like and automatically assume that she likes it and don't take her to a fast-food joint (i.e. McDonald's), unless she likes fast food. When you go, you should dress formal or formal/casual. I find that going straight casual kind of ruins a date, but maybe that's just me. It could do it fo you. Hopefully, with luck and time, the girl might want you to be her boyfriend. Now here's a catch: NEVER, EVER assume that just because she accepts you as a b/f that you can have sex with her. Many a boy (and girl) do that and end up being parents at a young age. It may sound absurd, but I'm warning you now as a precaution. I hope my tips help you. These are really just simple tips mixed in with my own experiences (which are few and far between, but are there just the same). I hope that whoever you'll be with stays with you a long time. God Bless!
