Since you asked, and I am sure others do not agree, shirtless pics, those in bikinis, minis, booty shorts, Daisy Dukes, etc. can mean a lot, or nothing. Some people do it because they have, as said before, with from super-sized to right-sized and they are proud of it, why would they do it if not to be seen? As said in a past thread about getting made up, if women will get all dolled up just for themselves, a person can take pics of themselves to make themselves feel better. Some do it to sample the waters as to how hot and boinkable they are, seeing that is rather important in this society today. They are not confident in themselves so they have to see how many positive comments or ”likes” (if that is what they call them, I have not been on Facebook in a couple of years) they get. Some are ”sexy and they know it”; why not use what Mother Nature gave you before Father Time takes it away, when he takes he rarely gives any back. IMO excessive might be if they have more than 20 pics and by proportion 80% of their total pic is shirtless, in bikini, Daisy Dukes, etc. Why have a sculpted attractive body and not benefit from it? That would be like having a Van Gogh you keep in the cellar for just the mice to see.
