Need Girl’s Pegging Insecurity Advice

So I’m new to getting into pegging with my girlfriend. I have this mindset of “sex is usually enjoyable if there is physical pleasure involved” so because my girlfriend is wearing a strap on, she doesn’t get ‘physical pleasure’ out of it

Because this is new to me, I feel kinda awkward about my girl being up my ass and not “getting anything” out of it. I think to myself “she doesn’t feel anything and probably thinks I look goofy”

So here’s my question for the girls: what is the appeal or gratification you get out of pegging men?
