Agree with Stranger and Mercury here. Yes, sex can and does get better as you get to know each other, but if something is wrong in terms of attitude or if preferences are a long way apart it will become apparent very quickly.
The thing about him asking why you are so shy, it's difficult to tell whether that's a bad thing without context/tone. If it was him asking out of concern or to reassure you that you were in a safe and secure place and there was no need to be shy, that's one thing. If he was asking to put pressure on you to be less "shy" and give him a BJ, then that's something else altogether. And it also depends on how he asked - if you were both asking each other what you like in bed, and he mentioned that he liked BJs, again that's one thing, but if it was just him saying that was what he wanted you to do, then that's another. But there are things here that should possibly be red flags for you Broken, but only you will know how these things were in reality.
Lovely lovely e-mails from Alpha today. I think he has got it bad .
