Drink responsibly, or you might fall victim to whiskey dick.

There are few men of drinking age who havent experienced some performance challenges after a night of heavy drinking whether they struggle to get an erection or reach climax.

In the moment, it feels like your body has cut power to your penis at the worst possible time, said Garrett, a 32-year-old sales executive from Seattle. (Many of the men who spoke to HuffPost requested that we only use their first names to protect their privacy.)

I think its my brains way of saying, Hey, youre not sober enough to use this responsibly, so Im gonna turn it off for a bit, he told HuffPost.

Because his partner handled it well the first time it happened, Garrett hasnt fretted too much about it since.

The girl I was with had a huge impact on how I felt about it, he said. I couldnt get an erection, but she was completely understanding and said it was normal and shut down my apology in a really positive way. I was really grateful for that.

Kelvin, a 31-year-old from Sydney, said he can get his motor running after over-drinking, but getting to the desired destination with his partner is touch-and-go.

Its much harder to reach full operation after drinking, he said. It takes about 25 to 30 minutes instead of the usual 10 to 15 but the destination is eventually reached. My apologies are usually duly offered to the passenger.

A quick apology and an understanding partner are ideal, but still, once youve experienced whiskey dick technically known as alcohol-related erectile dysfunction you dont want it to happen again. Below, urologists and sex therapists explain the phenomenon, how to avoid it, and what to do in the moment to get back to the business of boning ASAP.
