I had to spend hours training Instagram not to show me endless pictures of hot shirtless guys when I go to the 'explore' feed. I follow one or two pop singers who sometimes post sexy photos, but for the most part I just follow people that I really know. I'm not sure how my feed ended up so sexualized. My theory is that Instagram notices that I spend longer looking at hot guys when they do appear than I do looking at other kinds of photos. (I am happy to stare at hot guys, but it's not what I'm actually looking for when I go to Instagram.)
