it depends really.. i seem to fluctuate between 2"-5" when flacid.. depends on how warm it is.. nervous.. turned on... etc.
sucks cuz yeah, even though I pack a big hammer when erect, sometimes when I'm just chillin its like I'm packing a peanut.
I guess I'm what you call a grower.. some dudes are a shower, they are always large, flacid or erect.. but some dudes look like nothing, but once they get turned on.. KABOOM look out!!!!!
