How do they know?!

I have an above average penis (over 8 inches in length) and people seem to have picked up on it, even though I've never told anybody I know IRL that it's larger than average. 4 people I've known have said things to the effect of "I bet (my name) has a big penis!" There was one girl on high school that often said things like "I bet if he whipped his dick out, 90% of the girls in the school would wanna have sex with him!" and "One of these days he's gonna whip that sucker out put you guys to shame." And at that point it would take all my concentration not to get a boner in the school cafeteria, cause I REALLY wanted to fuck this girl, she had a great rack, ass and cute face. One person said they thought that I was big in the pants because of my low-pitched voice. It could be my bulge, but then again I always wear baggy pants. Not to hide anything, just cause they're what I like to wear. Although I do remember a female friend of mine back in freshman year saying she could see what she called my "camel toe," so maybe I do show sometimes without realizing it.
Anyone with similar experiences?

 

lockerrooms
showers
urinals
skinnydipping
reports by lovers, lays, groupies
chatty brother/s, sisters

in short, word gets around

 

for me, if you have long fingers, then it must be long i suppose.
the circumference of your penis is measured if you form a circle using your thumb and index finger.

 

good guessing!

 

ERRONEOUS!! Erroneous on both counts!

 

Nothing like your situation, but I've had guys tease or joke that I have a big one. Not sure what they based that on other than being tall and fairly big. Maybe it was from judging my bulge, but I never understood that. I never seem to notice this on guys, and if I notice the outline of a penis I can't tell how big it is. (Or is the fact that I see anything enough to conclude it's big?)

A previous girlfriend of mine would never notice women with nipples showing. I guess I've learned to notice these things. So maybe it's the same with women noticing men's bulges which I rarely notice.

 

It might be the way that you walk. I have noticed that some men with larger than average endowments, have a very eye catching walk. It's a body language that you can spot a mile away if you're one of those people that finds the way people 'walk' attractive.

If I see a nice lookin' woman walking down the street, I mean really struttin', then I tend to think, "Damn, I bet she can put it down in the bedroom." A sexy walk just makes wonder about what's in between someone's legs. I can't explain it anymore without sounding morbid, I guess.

 

It sounds like they are basing all these comments to you from observation; "I bet if he....." etc.....dude you must be showing an outline or a bigger than average bulge than most guys.
You did not mention any first hand accounts from girls.
I remember that with some pairs of jeans (ones that fit a little tighter) I can get some very nice eye opening reactions from girls, not that I'd let those reactions go to my head...no way not me....lol

 

Ever take a shower in the locker room? Take a leak in a restroom? Word gets around.
