Why would a man keep sending me photos of him shirtless in board shorts?

It’s a man I know. Is he trying to turn me on? He’s very handsome and has an excellent body, but I admire it like I’d admire a painting. Not having sexual feelings. I’m bisexual with a preference for men, but this man isn’t a very nice person.
