Why do I get horny/hard when tired?

[(hn)]

Not sure if this should be in the HF forum, but this seems to happen the more tired I am, especially the nights when I get 1-2 hrs or less sleep.

Is it just me?

I watched this thing on 60 minutes the other night and they said when you don't get enough sleep you lose sex drive. For me it's the exact opposite, I feel like a sex-crazed animal when I don't get enough sleep.

I tried searching online for this, but I couldn't find any reasons as to why. I'm curious to know why it happens.

This is gay.

Probably for the same reason some guys have to drink alcohol to be able to fvck some chick.

You are in a relaxed calm state.

In other words the 60 minutes study is bs like most studies are.

I get hornier when I'm hung over, but then I'm too sick to fvck. Oh well.

When you are in a relaxed or tired state your body activates the parasympathetic nervous system which thus activates the innervating nerves to relax the blood vessels in the penis, erection is thus attained. However during ejaculation the opposite happens because you are in a highly excited state.
