Enough sex to scare me.
Ok here's the situation I'm 20 and my girlfriend of over a year is 17, we love each other and have a ridiculous amount of sex. I get worried that one day either one of us is going to flip out because of feeling like we are just together for the sex, or being used. The thought she is with me for sex has crossed my mind already, but I never said anything and maybe she has thought the same thing and it bothers me. I know it seems crazy to worry about but we have sex so much I'm scared our love could turn to lust. Can that happen or do we just have an intense attraction? And does a lot of sex make for a healthy relationship?
