Not interested in sex with hubby

How do I explain this to him?

There isn’t anyone else, I’m just genuinely bored of how we have sex. I have a ton of toys that I happily use with no trouble. I’ve told him that I need more than to be randomly groped during the day. As if that were enough foreplay. He’s obese, to the point he has gotten smaller down there. Sometimes I don’t feel a thing. I don’t feel anything at all if I get on top. There are positions I want to do and he just can’t because his belly and small size won’t reach to me. I turned some red lights in our room to do something different and he said “this is weird”. And if I ask what he wants he says nothing in particular… shower sex is a no, sex during period is a no, car sex is a no, he gets tired on top. It’s just… plain boring. I’ve had crazy sessions with my toys by myself at home and I leave myself satisfied. I yearn to have sex, wild sex, there are things I would like to do that I simply don’t feel comfortable asking because I’m sure he’ll mock me. I just don’t know what to do. I can go weeks without sex and not miss it. I’m freaking 33, how is this to be the rest of my sex life when I thought it would be better at this age? 😖
