Well, obviously MN would erupt. However ....
... @ineedhelp37 has posted an honest question that she needs help with. I don't think an easy, straightforward answer exists, but that doesn't mean the question shouldn't be asked.
I honestly don't know what to suggest. Not in any way to derail the thread - I'm male in a sexless marriage. Is it because my wife finds me unattractive? I've no idea. If that were the reason, would I want to know? YES! Because the alternative is living a lie.
So - if my wife said to me, "The reason we don't have sex is because I find you unattractive," my reaction would be firstly to clarify what it is about me that is unattractive to her (note I don't say "isn't attractive"), then to decide whether I could do anything about that, whether I want to, and whether I think it'll be worth the bother - because, after all that work, it may turn out it wasn't my body that was unattractive.
If we decided there was no way forward sexually, then we'd have to decide what to do. This could be divorce, an open marriage (not a great prospect for an unattractive 45-year old (or in my case, 5x-year old) male), or - we carry on living together, celibate, sharing the house or doing our own thing.
I should add - I've had years to come to terms with my sexless state and I've been through every possible option, so being told I'm unattractive probably wouldn't bother me as much as it would some.
The big danger is doing nothing. Resentment and bitterness will build, probably on both sides. This is a waste of two lives.
The OP could have therapy on the basis that this is unlikely to fix the problem, but may open up a path to her that she presently can't see.
