It all depends on the guy's attitude. I'm no cougar but was approached several times at the pool by younger men. All is in the attitude. Once one of them got rather close, and was sexy even though 20 years younger than me, but his attitude ruined everything so I clammed down. Couldn't stand the cockiness. Never done it before but all is in the attitude. The answer you're too young is a generic answer. Depends on the tone and way it was given.
