This is my first post, more of a question really. I've been going out with my girlfriend for 7 months now. Outside bed we get along great, almost like kindred spirits. But in the bed ... it's a different story. We aren't like the typical couple, in fact quite the reverse. She reaches orgasm quickly (3-7 minutes typically) then becomes sore afterwards for several minutes. Me, i'm unable to reach orgasm easily, it usually takes me a good 30 minutes. She doesn't have the stamina that i need with her hands, vagina, or mouth so i usually end up masturbating. I do not masturbate unless i'm unable to orgasm with her (not even on my own time away from her). We don't live together, we see each other on the weekends and we spend the night together. Also, over the past 3 months or so I've become disenchanted with her, and i can no longer see her physical beauty.
I'm wondering if i should leave her or stay. I do love her but i'm finding myself wanting someone more, someone better for me. I'm still with her and yet i feel guilty even thinking about leaving her, but i want to be happy.
