I've been scared into staying by the same kind of comments by supposedly well-meaning people.

It's true- the women will be like sharks attacking him in the dating pool.

And I will always feel like a failure who couldn't even just be content.

The thought that now at 50 I may really never have sex again is sad and terrifying.

I really don't ever want to have it with him again, though, anyway. So, if I stay with him and never have sex again, then what good did it do to stay?
