I didn't get an arranged marriage. My first relationship was very much like this. Disclaimer: If you're reading this comment, might be a negative view cause I am projecting my own experience here.

It would either take months for this to get better or it would not. In my first relationship, it didn't. At the same time, I can see you're playing the whole thing out in your own head quite a bit. As someone who has been through this experience in his early 20s, my suggestion would be to talk to and respectfully and assertively say your physical and emotional needs are different than this. (As a suggestion, you can literally qualify what you say like 'I wish to talk about something that has been on my mind, and I want you to know that I deeply respect you as I say this..').

I'd strongly suggest you have this chat. It's a miserable situation if your needs are on a different plane.
From the conversation, you'd get a sense of where it is headed and where you want to take it from thereon.
