girls want you to be good in bed but being good at sex and having a big dick are not mutually exclusive.
Well as a female I say Yes that size is important BUT it's not usually the "deciding" factor. You gotta be good at sex. If your small and can work it..all is good. If your hung and can't work it...all isn't good. It's the "I can't find it" size or the "ginormous" size that is gonna be shit outta luck. Too small=Can't feel it OR Too big = pain instead of pleasure. At least IMO.
---I hate being suspicious about everything but that gut feeling is always right.
