Josie, that's pretty stereotypical...
A lot of guys really do care. I know of a couple where the girl was trying to push sex onto the guy. He kept saying no though because he wanted to make sure that he really loved her. She broke up with him because of it. He is now in a lovely relationship with one of my friends and that girl is now pregnant. So not all guys only want to get in a girl's pants.
Anyway, I do have great respect for the people that say to wait till marriage. But, if you really do love someone and you are old enough and mature enough, sex can be a great way of expressing your love. Marriage or no marriage. Many people in society don't even go off of that though. Sex is a game to many. I happen to still be a virgin and am waiting for the right guy to come into my life. But I also believe in sex after marriage. Wish all guys out there did too.
