Just wanted to check in. You sound like you are giving up. Are you? Your H is being a d*ck. In what he says and what he does - "entitlement" makes sense.
For reference, in my previous M my H had a big sense of entitlement. Swallowing felt too intimate in that scenario. I have no problem swallowing with my current H. He loves it and I enjoy it too.
Of course, everyone is entitled to their preference. I think if one isn't sure of their preference then it behooves the R to try it and see. As has become clear, swallowing is not the issue in your R but I'm not sure that your H's current feelings reflect a permanent condition. Hang in there!
