My girlfriend thinks all I want is sex
So, we've been dating for a year now. The first 6 months were amazing, but ever since then it's gone down hill ever so slightly, and now it's taken a turn for the worse. It seems like she is losing her sex drive completely. Any time I say anything at all about anything relating to sex she says all I want is sex and that she doesn't care about it at all. We see each other 3-4 times a week, we both live with our parents, we're in college together. Sex is DEFINITELY NOT all I want, though I think it is important in a healthy relationship, disagree with me if you want but that's what I think. We get along great, and we have fun doing a lot of other things. I don't understand what the problem is now and what could have changed between then and now... This has really got me down. Any suggestions would be very appreciated.
Oh and neither of us were virgins before we started dating, we both have had sex with 1 other person, both were in our previous relationships.
