My girlfriend wants to have sex more often than me.
I'm 22, my girlfriend is 24. Her sex drive is higher than mine. She wants to have sex probably every other day and I only want to do it when I have that urge... seems to be once a week. I used to watch porn before I was with her, she made me stop. We've been together for about 3 years now. In the beginning we had sex probably 2-3 times a week. I'm NOT watching porn on the side, I'm NOT cheating on her with somebody else, I'm NOT depressed, I DO FIND HER ATTRACTIVE. She is depressed because I don't want to have sex as often as she would like. We spend all day together because she has a part time job and I'm still in school. We have our own place so nobody is around to bother us. I love her very much. I want to spend every second I have with her. I love cuddling with her and holding hands, etc... but when it comes to sex, I'm just not as interested in it as she is... Any input would be greatly appreciated. Thanks in advance.
EDIT: She has had two previous partners and I've had two previous partners. We also purchased a vibrator for her, she was happy with that for maybe 6 months, now she wants more of me...
