I havnt taken a shower in gym yet... but im scarred to get hard and the other boys would laugh?

would it be normal if i got hard???

Yes, sometimes its normal for you to get a hard-on when showering. This is due to several reasons, and others can be explained scientifically

Usually, guys shower only w/ their underwears or none at all. THus, exposing your body to the environment (through radiation), This decreases your body temperature. Also, if your shower is a cold one, this also affects your body temperature to decrease (through conduction). So what would be the terminal effect? Your body tends to adapt to the new temperature in your environment, Also it tends to stimulate the blood vessels through your penis to dilate
This dilatation is also stimulated if you get excited. It is a parasympathetic response.

Also, as you noticed in a man's bathroom or shower room, there is a "diffrent" odor that you smell. Something like a musky smell. Its due to the fact that other guys had released or is been releasing their own scent together with their pheromones. This unique scent is released on their sweat through their armpits and pubogenital areas. Once smelled by the same sex, it signals the brain and send impulses to your parasympathetic nervous system having an erection. ANd it really is an unaviodable thing, unless you try to cover up your nose as you take a shower.

But just dont mind if you get a hard on or not. They should mind their own penises and not yours. If they do, maybe they are just some gay people who wanted to see other penises.
