Older women looking at me up and down!

Lately I have had a lot of older women staring at me . They are not just glances I have had several look me up and down. Whats every ones take on this. Is this normal?

The latest one looked at me and I made eye contact after she looked me up and down. She smiled and drove off.

I also wear tighter pants and i guess you can always see a bulge but i never notice!
