We've been friends for years and he sends me random photos, memes, urls to music we both like. Recently he has been sending me shirtless selfies (at least 5) one I could tell (short of being a full-frontal nude pic) he shaves "down there' lol. So why do you think he sends me all these shirtless photos, is this normal guy friend behavior? he says we are "friends" Anyone done this? have insight?
