Revealed: how pints of the black stuff make men BETTER in bed

Countless numbers of Irish women might disagree – but research has now revealed that men are, in fact, BETTER in bed after taking a few pints of the black stuff.

Yes, in her recently published book, The Married Sex Solution: A Realistic Guide To Saving Your Sex Life, Dr Kat Van Kirk highlights the four different ways beer-drinking guys benefit when it comes to getting busy in between the sheets.

And coming in for particular praise are dark beers such as Guinness.

Why? Because, explains Dr Kirk and as reported by askmen.com, the high amounts of iron contained in stout increases the amount of blood circulation to the penis. This in turn can then boost a man’s libido and lead to longer, more intense erections.

That's not all, however. No siree. Dr Kirk, a clinical sexologist and marriage and family therapist, also explains that beer ultimately supplies your body with plenty of phytoestrogens which are scientifically proven to delay orgasm.

Meanwhile, Italian researchers have found that daily beer drinkers have more stamina than their sober counterparts — and are 31 percent less likely to have heart disease, heart attacks or strokes (nope, we're not questioning it either).

Finally, Guinness is especially rich in probiotics and B vitamins, which are excellent for digestive health (because nothing says 'mood kill' like a dodgy tum). This also means "you won’t feel sluggish during sex," Dr Kirk adds.
