For someone inexperienced like me, how can you tell if you’re having boring sex?

So I’m one of those autistic persons who can’t count (sorry, Bob’s Burgers joke) and I often times don’t have the best grasp of my emotions and during sex I feel kinda weird because I don’t really do much unless I’m asked, so most of the time I’m just laying there (yes even during foreplay), and once or twice I’ve contemplated in that position just to have something to do. I’ve realized recently that sex is the weirdest position to look at someone you care about, like that thing about feeling butterflies in your tummy kinda dies once you see them naked or maybe I’m just weird.

Like obviously I know when things feel good and when things feel bad, and I knew when to say something was uncomfortable for me, but other than that I have to admit my feelings weren’t very clear about sex, and I only had sex in the context of a long time relationship.

So, any signs or symptoms I can look out for?
