I don't know if this trend towards sexting is normal, but it's certainly common. 😐
I remember talking to a guy several years ago (real life friend, sort of. We are no longer in contact) who was getting a divorce. One of the first things he did was take multiple pictures of his package because he'd need them for when he did online dating. He wanted to have them ready to send. He really thought this was part of his prep work, sort of like running copies of the agenda for a business meeting you're attending--it's just what you do. I said nothing. Let him find out on his own.
(He did get remarried last I heard. So maybe said package was/is more impressive than I was imagining)
