How does alcohol affect male sexual performance?!

It is not impossible. However, it does make it harder (I should say difficult, not harder) to get and or keep an erection while being drunk.

Take care!

Bit of alcohol helps.
Too much can cause an erection problem (I mean when extreme quantity of alcohol is consumed).

But it always comes to personal qualities.
No single male is same.

It's the difference between it watching him shave or it watching him tie his shoes.
This is a serious answer to a serious question.

Maybe it affects a bit. I don't really know because I've never experienced that, but some of my friends told me that alcohol made their performance terrible. They couldn't control quite well as normal.

it is not impossible as it is harder to get hard.
