Is it normal that i want to send photos

If not troll. And yes, means you are gay and sexually interested buut it would be weird to suddenly do this stuff. Be careful and do not act like an animal in heat :x
You could ask him carefully and not too directly?

That is a really terrible idea.

I don't think is weird but just sending them out of nowhere might not be such a good idea. Talk to him, go to a bar and bring it up and see his reaction. I would rather be smart about the approach to avoid awkward situations and feel bad after I did it but I do see the appeal of just sending them like that tho.

When I was in high school,I let a male friend of mine suck my cock. I have to say it did feel good. We were at his parents house,in his room,looking at porn magazines of women with big Tits,our cocks out,and jacking off

Take the picture without your face in it

Find out if he's gay or bi. Then in a round about way, u could offer it. Don't just send.

update - in one of our 'life chats' we got on to the subject of naked selfies, eventually he suggested I send him one as he was "fairly relaxed about sexual stuff".
He now has pictures and a close-up of my erection. He has since sent me a picture of his semi-aroused cock. I think i'll be tasting it soon.

Modern problems require modern solutions I guess lol.
