Should I be annoyed?

Boyfriend told me last night I need to do 200 squats a day so I can be better at being on top.

Usually he is because he and I like him being in control.

I think it's his way of passively saying I need to loose weight, which I am trying to do.

Right now I just want to hold off sex because sex with me on bottom is better than no sex at all.

I feel upset, do I have a right to be?
