Married 15 years. We were both obese. I then lost 90 lbs and she was initially supportive but as I became more invested in fitness she slowly began becoming less supportive.

She never initiates anymore, and she's made some comments about preferring me chubbier (I'm not scrawny, I lift and I'm fairly fit).

I'm tall and after losing weight I believe I'm moderately handsome, but that confidence gets rattled when she's never interested in sex.

I know a sexual relationship is way more complicated than just looks, but I get no validation from her and I'm now seeking it from strangers online, which obviously isn't ideal.

I want sex with someone who wants sex. I'm approaching 40 and I worry in a few years I'll be over the hill and never have that chance with another woman.
