It really isn't a matter of convincing a girl. Here's what the deal is:
Most young guys, once the hormones start flowing in puberty, equate those feelings and sexual urges to lust when it comes to a girl.
When it comes to girls, in puberty, having these same desires, they see it as a need for love and equate having sex with love. They need to have feelings for the guy and want him to have feelings for her. Sharing herself sexually with a guy is an act of 'Love' NOT lust for a female. So they easily become attached, and also they can be easily hurt, Especially if they find that a guy: 1. pretended to love them to get to have sex with her
2. Is the type to force her to have sex, using his strength to overpower her, or play mind games saying she needs to have sex to prove that she loves you.
Guys who are not genuinely caring about the feelings of the girl they want sex with, will end up branded as a player as girls start to share how they were 'USED' by a guy and all the girls in school near your age will know to avoid you which means, the only ones left to fool are the freshmen coming in and they've been warned that older classmen who want sex are probably not truly in love with them and just want to use them.
So the best thing you can do right now to take care of urges is masturbate. As a teen or even college age, if you have a girlfriend, either you are a good match as best friends and have sexual chemistry or you don't. If this is the kind of girl you could end up having feelings for that are reciprocated by her, then allow yourself to get to know who she is on the inside first, get to know her personality and characteristics. treat her like a princess and she will naturally come to a point of wanting to be able to express her love with you through one of the most wonderful ways a couple can.
Don't worry about life time commitment here. Romance and love at a young age rarely last a life time. Most likely both you and she will end up falling in love many times with different people you date in the future. But the love and caring is an important factor for most girls.
I know there are exceptions to how some people are but most people are like that.
So if it's not that you care about your girlfriend but all you want is sex with a girl, then for one thing, make sure to have condoms and also make sure the girl is using a contraceptive like the pill, which she can get from Planned Parenthood. If you can't be adult enough to take care of these issues ahead of time, then you're not mature enough to be engaging in sex. I do hear from the very few girls who are extremely horny and do want to have sex with a guy and are tired of just masturbation. Guys will usually pass the name of such girls around. These girls are more into it for the lust, but take care, they are very few and you want to be sure they don't think they are in love with you if they are agreeing to have sex.
