Flaccid hang--What would you stop at ?
Would you stop at 6 flaccid hang or would you move on to 7 or even 8 flaccid if you could? Flaccid 6 on up is probably going to cause problems with getting in the way when sitting in general and keeping it out of the water when on the toilet may require some care.
Would you be proud of a 7 inch hang or would you consider it a bit embarrassing when it shows everywhere you go no matter how you wear it in your pants?
