So I picked her up and she stayed the night. We had sex a few times, but I think we have a little problem. Maybe I am not long enough, though I thought I was, but doggy seems to be a problem where we cannot get the rhythm right. Also, I cannot seem to position side correctly as well. Cowgirl and missionary, she enjoys especially when I raise her butt in up. She likes it fast and hard in that position, but at the speed she likes it I cannot keep doing it for more than 30 seconds or my pelvic and lower back really starts to hurt. So far, she can only climax orally or with a finger, not with my penis as it takes a long time. After 2.5 hours, I gave up and climaxed.
Advice welcomed and encouraged. Concerned that the sex will become boring soon for us.
