I think I was dating my then-girlfriend for about three months before I ended up staring down the business end of her dad's shotgun. In time I ended up marrying her anyway, but her dad and I still aren't on the best of terms.
14 is pretty young to be thinking about sex. It's too young to fully appreciate the consequences, and even too young to fully enjoy the act. My general thought on condoms is if you think you need to be using one, you probably shouldn't be having sex in the first place. I've never used one and never felt any need to. Condoms aren't foolproof, and if sleeping with someone amounts to some sort of risk, then don't take that risk. Too many guys lack any self control and let their schlong do the thinking for them. We all see the consequences from such poor decisions all too often.
To put it simply....don't be a moron.
