Ego or what ?

I'm newly married, we been together a year.. He ten years younger than i. He currently trying to build muscle i liked that idea. He motivating me to excercise.. But, lately he started wearing muscle t shirts to work.. Just wondering if he trying impress ladies at work.. Do married men do that? Try to boost ego ? I'm always rubbing all over him sexually aroused around him that should be enough. Women who are married get boob jobs why ? To impress their husband or other guys as well ? I see women showing clevage and married why ? And short shorts. Just had it running through my mind. I like to impress my husband.. Only. I was Married to older man for 23 years... Now. Married to younger man i'm just learning.
