37 year old man and 21 year old woman hooking up?

[Medeguy]

I been single for 5 years now. I used to be married and now I only look for  friends with benefits situation. Not interested in dating. I  recently met this girl who is 21, I am 37, and shes interested in me, and made it very clear she wants me, now I am very tempted. But is the age gap too much?

Too much for what, exactly?

Casual hookups? It's probably fine. Serious dating? Unlikely to work out well.
