Advice needed: should I send another man an explicit photo of myself

OK so I've been saving this alt for a while now. And for privacy reasons I cannot use one of my other alts.

I recently attended a several day long meeting in another city. My wife attended with me. There was much late-night drinking involved. During one of these late nights of drinking, we hung out with a guy we met from the meeting, who happened to be gay. We had a good time and good laughs.

After many drinks, our new friend casually suggested we could all have a lot of fun in bed together. We all laughed it off and kept drinking. But as the night went on, the threesome suggestion came up again and again and his advances became stronger. It was obvious he wasn't so much interested the MMF... just the MM part with me.

It might sound creepy but it wasn't. It was fun. Our conversations were highly sexual in nature and it felt good to discuss so open and freely. And the fact that he was totally hitting on me was kind of flattering to be honest. He was quite a bit younger, and I'm not 100% straight (yes my wife knows this) so it was somewhat tempting... but when it comes down to it, my wife and I just aren't threesome kind of people. So to his disappointment I told him sorry, but it wasn't going to happen. So by the end of the evening a lot of unresolved sexual tension had been built up.

(Now remember that I had several drinks at this point)

So to ease his disappointment, I promised to send him a pic of myself. Yes, an explicit one. Something he could have to remember our fun evening, even though it didn't turn into the threesome (more like twosome) he had hoped for. He accepted this was what he would have to settle for. We all hugged (during which I gave him a squeeze on the butt), said goodnight, and went back to our separate hotel rooms.

So now I'm back home and I have not yet sent him a pic. And I'm feeling guilty about this. Because I promised him I would. But I also had a lot of alcohol and I would not have made this promise while sober. Part of me thinks, what's the big deal, just send it. I will probably never see him again. It would be rude not to. Don't be such a prude. But part of me says, what good can come of this? Am I sending it for him? Or for my own ego? I might run into him again someday, and even though I'd like to hang out with him, I don't want to end up in bed with him.

What should I do? Send it? Or forget about it?
