To the girls now I have never said this to one?

Now just remember I have never told a girl that and would never think of it but around school there is some woman that say they see it as a compliment

You are always safe with comments about their eyes or smile. Complimenting those will get you a lot further than comments about anything lower. Save the other curvy parts you love for the bedroom where they are more appropriate in context. Avoid any compliment using the word fat, it is seldom well received.

This is very girl dependent. I wouldn't like it if a guy called me a fat ***. I would prefer you have a nice butt

Don't tell a girl they have a fat *ss, or anything like that. We find it really rude and condescending. Go for something like "beautiful" or "cute". Even "sexy is pushing it.

Don't say it. Just keep it to yourself.
