Okay, so maybe you are comparing her to your wife. I met and had sex with Mono within a week but with Derby it took a month (?), with my husband a few weeks. I don't think comparing is going to get to the root of it. With some its instant, with others it takes time.
Really, I think you are creating a mountain out of a mole hill at this point. Why put it on yourself. So you aren't a big stud with her, so what, I'm sure she is having fun regardless, she came back no?
