An old flame sent me a photo of his penis day after I was messaging him about another guy. We have been friends since 91. He's married .We had sex back in 2014 for the first time since 92.
I was showing him a conversation I showed him with someone he knows I had a brief relationship with.
This guy was trying to hook.up with me.Aftwe sending him message of me and the other guy I never received another reply.

Well the next day after that through mess I had notification of a photo.The old friend sent me pic of his penis .I'm confused as of why when he stop texting me

You need better friends/acquaintances.

What's confusing about sexting? Or why would he be interested in some guy who wanted to hook up with you? Maybe he got busy with his wife for a day and they did married people stuff and didn't have time to text about some guy he knows that wanted to hook up with you.

You could ask him all these things. Or just sext him a picture back. Beats wondering.

As far as h being busy with wife he sent me nude photo I didn't send him .I was engaged in someone else
