Guys, what would cause a rock hard boner or blue balls?

A rock hard boner comes from arousal. During puberty, guys can get them for no reason at all. They can be just sitting in class and have it happen. But as they get older, it happens when they are actually turned on.

Rock hard is when their cock is a heat seeking missile that is locked on target and ready to launch. It feels like a hunting dog straining at the leash.
It's a really good feeling, but it craves fulfillment.

I've never experienced blue balls but here is an explanation:

Blue balls or epididymal hypertension refer to scrotal pain or a feeling of heaviness after sustained sexual arousal without orgasm and ejaculation. The symptoms of blue balls include mild pain, discomfort, aching, heaviness, and sometimes — as the name suggests — a faint bluish colour in your testes (also known as testicles).

What causes blue balls?
“When things are getting hot and heavy, the body channels blood into the penis and testicles,” Dr Rhys Young says. “The veins that would normally carry that blood away from the area restrict so that the blood stays there to create an erection.”

After ejaculation or when they’re no longer aroused, blood flows out of their penis and it returns to a flaccid state.

“However, if you are aroused for an extended period and don't get that release or drop in arousal, extra blood can stay around,” Dr Young says. “This can cause some pain and discomfort.”

When I wake up in the morning I usually have a rock hard erection. Also if I wake up during the night I am hard, so I think I get several hard erections during night while I'm asleep.

I also get a hard erection when thinking about sex or about to have sex. Sometimes I get a random erection for no reason, such as in the shower after exercising.

Blue balls are painful, they happen when I get aroused but don't have the release of ejaculation. My balls ache and feel like they are burning, it's very uncomfortable.

Early morning waking up, seeing a naked girl or a porno, touching a girls tits or pussy, getting a kiss from a girl you like, knowing that you're just about to fuck someone.
Getting REALLY horny and expecting to get sex and then finding out you're NOT getting sex.

Doesn't that make it fun?

[FunkyMonkee]

If you mean my answer to the first question, yes. NOTHING is fun about getting blue balls!!

Give him a BJ for 3 min then walk away

I get boners from general arousal and morning wood but rock hard comes from really good oral.

Blue balls comes from a build-up of sexual pleasure but without a release. The blood vessels build up blood pressure and the muscles are primed to shoot out jizz. So without a sexual release there's nowhere for all the pressure and energy to go.

Being turned on

[Pudsmucker]

The rock hard boner can be caused by you walking in the room and being naked.
You teasing me and not letting me totally finish off with you. And you walk away. Not letting me finish off what you started.

Stripping down, starting to play with yourself
