Don't get me wrong she's a wonderful girl, but we have now slept together twice, both times she tapped out before I came, and now I am left feeling sexually frustrated. We were both virgins (18 year olds) so maybe I am doing something wrong. The second time we tried we went for only 20ish minutes. I don't think I have a crazy high libido but its definitely higher than hers. I am mainly just asking for what I should do.
