Is it normal to send pictures of myself to other guys?

It's not normal, but I think I understand, even if it's a straight guy guy wanting to send pictures to other guys.

It would be easy to associate it with being egotistical, having low self confidence, or being a closeted homosexual.
But since your question was simple and to-the-point, I'd give you the benefit of a doubt that you are an open person. (Besides, you've heard the other side from every other comment anyway)

It's OK to be open, as long as you know the art of being subtle and considerate. Being able to show a guy pictures in some cases shows that you and the involved party have a casual sort of confidence that most people don't. But you need to have the right attitude about it.
What you need to understand is that not a lot of people are open like that about seeing you naked.
In most instances you could annoy people, or make them uncomfortable with you, or give them negative assumptions about you.
Also, they could blackmail you, or you might give a closeted homosexual friend the wrong idea, and that could get awkward.

I'm bisexual and open minded to that stuff, but I still believe people need to show respect and subtly when it comes to sexual things.
Personally I would never send a straight friend a picture of myself, it'd just not my thing. I've sent nude pictures to a couple of girls and a guy that asked, and that's about it.
And yet, all my friends (who are all straight, and most of them don't even know my orientation) have NSFW pictures or sex videos of themselves, and they are a little too eager to show them off to me and others with little consideration and the wrong attitude about it. They are either just fishing for compliments, being egotistical, or doing it as a shock prank.
Rarely have they been level headed, considerate about it, or wanted honest mature feedback. Even though I'm bisexual, they are still just my friends. I'll look at it because we're close friends and I can give you feedback, not because you think you are so sexy that people would be honored to see you naked, and would love to air-pump your ego.

It's OK in my book, just be considerate about it.

Im with Ramit10, send me sum2 i''ll let u know wat i think.

Send some to me

Is it consensual? I mean, do the guys know they're getting a picture of a naked man? Or do they request it, even? Nudity is nothing to be ashamed of. I'm wondering if you're questioning your sexuality, though.

Because you have low self esteem, so when you send them naked pictures and they say shit like "Oh you're sexy" it makes you feel better about yourself. Please have some self respect. You can feel good about yourself without having to send guys naked pictures.

Are you in a relationship? If yes, well I got no respect for you. If no, do whatever you want.
