As a man: Pretty much yep

It's like it gots a mind of its own, especially in the mornings.

I don't know about any other guys, but I get random boners, like for instance: Hey look that's one hell of a sexy tree! and then I get an awkward boner...

To iceshard: Don't worry, normal boys go through this in puberty. Did you not learn this in health class? I'm a girl and I know this.

I find that if I havent came in the 24hrs, I can pretty much think myself into an erection without having to lay a single finger on it. Especially in the mornings.

What'sa matter, boy? Are you dirty, boy? Ok, let's go to the shower, boy!
