Woman laughing about penis size of boyfriend

Is your man average?

A new study by Indiana University reveals a lot about a man's penis size.

How does your man measure up when it comes to his business downstairs? Until now, you had to either compare notes with your girlfriends or do your own "research."

50 Crazy sex facts for the modern woman >>

No need for that anymore. A new study of 1,661 men finds that the average penis size is 5.6 inches with a 4.6-inch girth while aroused. For the study, which was published in The Journal of Sexual Medicine, Indiana University's Debby Herbenick asked participants to measure their penis length and girth and submit the numbers online.

The results? Common "predictors" of penis size — race and sexual orientation — are myths. Also surprising: Not all erections are created equal. According to researchers, men who achieved an erection through oral sex reported a bigger penis size than those who got aroused through fantasizing.

"The average penis size is 5.6 inches."

"We don't know if that means that when men have oral sex that it's more arousing and they get a bigger erection, or means that men who have bigger penises could be getting more oral sex in the first place," Herbenick told LiveScience.

Naturally, there are outliers in the study. The smallest penis came in at 1.6 inches, the longest at 10.2 inches.

Next up for researchers: measuring women's genitalia size.

"It would be good for women to have good data to show, 'Hey, there's a lot of diversity for women's genitals, just like there are for men's,'" Herbenick said.

I'm about average. I had a prostatectomy (prostate removal) and now use either caverject or . With caverject my erection is bigger than it was before and my wife comments on this regularly, "You're really filling me up!"

My man is a little bit more than 7 inches, I feel really lucky, he knows how to use is ;).

Sure some men have a small penis. But at the same time, some women's vaginas are just too big...

The thing about oral might be true, though sometimes after long and tiring , the next day my penis seems to be a little thicker, maybe from the veins being stretched out from being so hard for so long? I think the oral thing might be related to how a penis pump works. I know when I'm not in the mood, my lady will give me oral and make it hard enough to complete the action she's craving. But when I am in the mood, it does seem a little bigger (longer and thicker) than usual, but also maybe because I'm more turned on than just thoughts alone, though really good foreplay makes it bigger than normal hardness too. Just a couple of thoughts.

My penis has a huge difference in size from flaccid to erect. It sucks because it's been like 3 inches at times, not often but that's small. Then when hard, it's like the Hulk and gets over 16......cm big, haha. I think that's about 7 inches. I've seen some in porn that are the same size almost in both states. At least mine is perfectly straight and cut. Those cold days though. Don't forget to manscape guys, you can gain an inch or two.

don't believe in these article reports, because their was a study that was done in America that said that the average was 5.08 inches with drug injections, so I'm guessing it's 4.88 inches without any here's proof http://www.ncbi.nlm.nih.gov/pubmed/8709382?dopt=Abstract

I always thought that there were a lot of men's with 8 and 9 inch penises but that's porn not reality. SO i thought that my 7 inch with 5.5 girth is unequal but right now after doing the research I thought is 6 inch is average but after reading this article it's 5,6 inch. I am realizing that I might have problem in future I do not want to hurt my partner with my size. Because I know it can hurt girls. I don't want my future girlfriend to suffer from pain. Because I read somewhere in my health class that vagina is no longer than 6 inch.
