i have heard of a guys penis is hard what exatly does that mean im was told 2 different things , whats your explination

[Luisss]

When it's "hard" it really means it is erect. When erect, the penis is stimulated and blood rushes into the penis making it firm and stand away from the body. Yeah so when hard it is an erection.

That it is hard enough to penetrate a girl

[Matt169]

When it is hard it literally means it is HARD, the entire penis goes hard and grows in preparation for penetration

[Curious.kid]

It stands up and isn't soft or loose. It feels really good.

It means the the blood goes into the penis and makes it hard and erect

[douglaseverett1998]

When it's hard, it's literally hard. You're erect, it's full of blood.

[mattjh-]

It means he has an erection. When a guy has a boner his dick will become hard like a rock.

It means he has an erection

[DylanAwesome]

It's when the guy is aroused and blood fills his penis making it harder and longer
