I know this is probably not what you were expecting to hear but your story actually gives me a kind of optimism.

I'm a guy who's never been in a relationship because I won't have sex. And that's kind of shaped my perception of what relationships are like. Namely: they've all got lots of sex going on.
So to hear that there's even just one guys who's had a steady relationship for 15 years and been married for four without sex being too big of an issue is kind of amazing to me. It gives me genuine hope that one day a girl will understand why I am the way I am.

Hope you find a good resolution to your issues, cheers!
