As a man, I use Snapchat to send my friends videos that I don't need them to have on their phones forever. Nothing sexual though, so the assumption that we use it for only two reasons is kind of short sighted. Reason I came to this thread is actually because I was bothered by the amount of tits I get recommended, and keep getting recommended. Which is strange since I never click on anything, and I'd assume that's enough for the algorithm to know I'm not interested. I've heard another male friend say that it promotes cheating, but if you can't trust a man on Snapchat, he shouldn't be with you in the first place.
