Heard of the term “whiskey penis”?

The theory based on when a man who has had too much to drink can’t get an erection when the opportunity presents itself. But here’s the thing, we’re not talking about whiskey. We’re talking about our good old friend, our liquid wingman, oat soda, Homer juice – you guessed it! Beer! According to Dr. Kat Van Kirk, sexologist author of The Married Sex Solution: A Realistic Guide to Saving Your Sex Life, beer lovers, should be happy to know that beer actually makes you awesome at sex.

Beer provides a man with four different benefits right before he hops in the sack.

Delay of premature ejaculation.

In line with the theory of whiskey penis, drinking a couple of cold ones overloads a man’s body with phytoestrogens from the alcohol, something that Van Kirk says are proven to delay an orgasm.

Boost in libido

For those who enjoy drinking darker beers, the second benefit is longer, more intense erections. This is due to the high amounts of iron in dark beers, like porters and stouts, which increases the amount of blood circulation to the penis, which is great for an erection.

Increases Sexual Stamina

The third benefit of beer drinking, according to the European Journal of Epidemiology is that cold brew increases your sexual stamina. Researchers also found 31 percent of moderate beer drinkers had a reduced risk of cardiovascular disease compared to non-drinkers.

Fortify Your Health

The final point Van Kirk makes is that, after a night of drinking, the one problem some people have is nausea or vomiting. Since beer contains loads of probiotics and B vitamins, Van Kirk said beer “can help fortify your overall health and be better on your stomach so you won’t feel sluggish during sex.”

There’s even a beer brewed specifically to help people be better at sex called 50 Shades of Green. This beer contains 50 kinds of hops and other ingredients like ginseng, ginkgo biloba and damiana, which, according to the brewer, will increase sexual desire, blood flow, and nerve stimulation to drinkers.

Remember though, moderation here is a good thing and as much as you’d like to reap the benefits of beer. Nothings going to turn you into a stallion over night. A 2 or 3 drafts should do the trick. Anything over and you’ll probably end up with whiskey penis, not to mention an unhappy partner and a major hangover.
