Is A 3&1/2 Inch Flaccid Penis Normal?

Absolutely normal, and quite big when erect, lucky guy, cold will make it shrink and retract for warmth.

This is a normal measurement majority of men been the same also when your cold it will cause your penis to shrivel and go right back, or you may have too much fore skin in which case you could have a circumcision removal of the fore skin to improve this its a procedure done very routinely now and your home within hours

Flaccid sizes don't count there is no average flaccid size
it is the erect size that matters and you can only have sex if it is erect
a 7.75 inch erection is big and a good size for sex
what you havent said was your age then the answer will be more accurate

Lol. Don't worry dude. It's totally normal.

  It sounds like you're a bit obsessed with this normal thing. There is no way that you can accurately measure a flaccid penis. That's just like the weather, if you don't like it just wait five minutes cause it's most likely going to change. You decide normal by looking at what you have and that my friend is NORMAL. Normal for you is not the same for the next man. Close maybe give or take but still not the same!

O_O Sure, home within hours, but not walking normally for a few days at best... That's a pretty sensitive area to be whacking a chunk off of, and just going home and partying afterward! Sheesh.
 Look, this is perfectly normal. Some guys hang low (with little penile retraction after erection has subsided), some guys go the natural turtle way (full retraction, giving the impression of smaller size).
 Neither is more 'normal' than the other, and it has nothing to do with erect size, and lets face it, that's what actually counts, eh?
 You are not alone (I am built the same way), and there's nothing to be concerned about.
 Hope this has helped. Have a great day!
