Or underwear/revealing pictures.
I was just on Instagram and ended up on one of the Love Island contestant's pages.
There were a few revealing pics of her in a bikini or in underwear, and I was able to see that it was 'liked' by a male acquaintance of mine, who's in a long term relationship and has a 2 year old child.
I know it doesn't mean he's cheating, but I'm not sure how I feel about it really. Sure, we all think others are attractive, but is it necessary to like revealing/almost naked photos? Maybe his partner is ok with it, who knows. I just find it a bit disrespectful.
