We happen to know a lot of doctors. We asked around a few common questions about boners and we came up with these 10 facts about boners every guy should know.

Men like to brag with their friends and most of the information they share is WRONG. So read carefully.

1.You Don’t Need To Be Born To Get A Boner

2.Boners Come In Three Flavors


Not in the sense you are probably now thinking… There are three different types of erections. Psychogenic erections are those that come about after fantasizing or watching something that gets the juices flowing. As the name suggests, nocturnal erections are those experienced at night. Finally, reflexogenic erections rear their head after some physical hanky panky.

3.Speaking Of Bedtime Boners…

Men are typically frequented with three to five bouts of “nocturnal penile tumescence” as they slumber. That’s still nothing on the 11 towel racks the average man puts up throughout the day.

There isn’t really a consensus over why the penis likes to stand to attention at night, but it’s thought to help keep the tissue oxygenated and thus healthy.

4.There Is Life After Death

Delightfully named “Angel Lust,” if a man dies in a vertical position, the body can end up with a post-mortem erection. In the absence of a beating heart, gravity will cause blood to accumulate in the legs, and as the vasculature in the legs gets filled up, some of the remaining blood in the body gets forced into the penis tissue and makes it expand.

5.The Average Erect Penis Length Is……

But there was not just person-to-person variation: How the participant attained an erection was found to affect the dimensions of his junk. Perhaps unsurprisingly, they tended to be longer after sex when compared with those that popped up after fantasizing.

6.Pass The Donuts


Smelling delicious things can make the senses go wild. And the penis according to a study, the scent of black licorice and donut can ramp up the flow of blood to the penis by almost 32%. Mixing up the odors of donut and pumpkin pie caused an increase of 20%. Weirdly, it was actually the combination of lavender and pumpkin pie that had the greatest effect, causing a 40% rise in penile blood flow. The key to a man’s heart may be his stomach, but clearly the way into his trousers is with fragrant baked goods.

7.It Might Be Called A Boner…

Always use protection

The penis does not actually contain a bone. That’s in contrast to the majority of mammals, which sport a baculum to help with getting jiggy and sperm deposition.

8.The Never-Ending Boner

There is an unfortunate condition called priapism in which men experience an erection that just won’t go away, lasting for at least four hours. That might sound like fun and games, but they can actually be painful, and aren’t necessarily the result of sexual stimulation. Awkward.

9.The Penis Is Boomerang Shaped

It might look straight, but we know that it is indeed boomerang shaped. The reason it doesn’t appear that way is because part of it is hidden by the pelvis.

10.Looks Can Be Deceiving

“I’m a grower not a shower” actually has some truth behind it. Smaller flaccid penises, according to a study conducted back in 1988, actually experience greater increases in length during an erection than large ones. It’s always the shy ones…

So there you have it. The hard truth about boners.
