No idea what cougars want

Hi, I’m a younger guy; 21+ and I came to terms that I’m just helplessly, deeply attracted to older women and I don’t know what they’re into.

I enjoy talking to them and they do as well with me, I’m generally a polite, good reliable guy in general, so I’m often well liked by Them.

How do i approach them?

Do they like e slender/fit physiques or should iput some muscles on?
