My girlfriend an I used to have a satisfying relationship on all levels. When it comes to having sex, I'm pretty much into everything( except peeing or sm), while my girlfriend always liked to soft approach. This doesn't implie bad sex for neither of us, she has like 4 or 5 orgasms during sex and I'm crazy about all her body parts (esp the butt)So for six years both of us were satisfied with it. We had sex app. two times a week, and when I felt horny and she wasn't really into having sex, most of the time she gave me some head.
One thing that realy bothered me was the fact that she doesn 't like wearing sexy lingerie and showing this to me, although I tried convincing her she's a real foxy chick, with a great body that really turns me on. So from time to time I brought home sth I would love to see her in it. But nothing changed, so I kinda gave up, thinking the actual sex part was still good. But a few weeks ago she came home from this upper dare party (woman friendly porn toys sold at home) telling me she had bought lots of nice stuff, which I would appreciate very much. And indeed: one week later later a package arrived with a damn kinky lingery set in it and a extra thong. I was damn happy with this and thought the problem would be solved for now. However after having it in her closet for more then a month now, she hasn't wore it a single time. After this dissapointment we had a pretty big fight about it,and since then everything else is fucked up too. So last night she finally slipped into something sexy, but it didn't arouse me at all! I now have the feeling she's way too late. What should we do?
