I will tell you the best thing you can do:
1. Don't even start dating until you are 16, plus it's better then anyways because what are you going to do pick up your girl on your bike and take her to the movies? Chicks like cars

.
2. When you turn 16 and start dating go on group dates they are a whole lot more fun and you get to know what kind of girls you like...plus it helps prevent the chance of your horny a$$ getting some girl pregnant.
3. During college you can single date but try not to have a steady girlfriend unless you are absolutely sure that she's the one because damn that must suck going out for 4 years then BAM she leaves...my condolences dude.
P.S. I'm only 16 but listen to me I'm very smart I had to learn a couple of these things the hard way...no I didn't get a girl pregnant...luckily. But I have had steady girlfriends who I thought I loved damn infatutation...they leave and you feel like sh!t and go all depressed and nobody likes to be around you. Just follow the steps and trust me you'll be happy.
