Sexy Nephew!

I wonder if any aunts feel the same! My nephew is 26 years youger than me (my sister's son). Growing up he was a cute but sometimes annoying child, then a very cheeky teenager. I was not particularly close to him until recently and I cannot believe the pleasant fun young man he has become. It feels awkward to say it, but I do find him very sexy...oops! My husband has lost all interest in me and treats me like shit. All I can think about is how good it would be to have sex with my nephew. oops! Is anyone in the same situation?
