Me and my girlfriend have been together for a year and a half. We talked about getting married and everything. This is my first serious relationship. We're both 18. I'm in college and shes about to graduate high school and still living with her parents. Our mentalities are very different. She gets mad that I go out with my friends and feel that I choose them over her. They are the type that go to clubs and party but she is not like that so it is hard. She says I don't care about her anymore and don't do things to show that I love her like I did in the beginning of our relationship. I do love her but I have a hard time showing it lately (doing romantic things). Recently I've been craving no-strings sex with other people. Not that I've done anything though. I am a very sexual person and want to explore my sexuality but I can't do that with her. Our sex has never been that great. We would only do it with me or her on top that's it. She refuses to do it from the back because it 'degrades her'. We used to do oral but we don't anymore because she is 'saving it for marriage'. What? We lost our virginity to each other and that's something I want to value. But maybe we're too young or we're not ready for a serious relationship. I feel like breaking it off. Should I start being romantic and hold back my sexual desires to save the relationship?
