I'm going to answer without reading comments first.

What do I like about men?

I like eye contact, no doubt.

I like their playfulness in flirtation.

A strong handshake, for some reason that gets me, when/if that opportunity arises.

I do find that I prefer them taller than myself, gives me a sense of protection even if I believe that I can protect myself.

I like their subtle insecurities, though they can be bigger than me, it's a vulnerability that balances the power scale.

I like a good sense of humor in them, some form of flattery and if they like sports, even better.
