Men that stare at women from head to toe?

My friend , Was talking to me . And as he was talking to me he was looking at me from head to toe , Up and down . Of course he's flirty at times . But I was saying to myself what is going through his head. Because he never said anything sexual . He hugged me and said I will talk to you later . He knows I'm in a relationship , But he's been doing that a lot lately .
