I'm a grower and, frankly, always wanted to be more of a shower. I'm well above average (7.5 x 6) when hard, although not up to the size of many on this site. But flaccid, I vary anywhere from 3-5", and not nearly as thick. I'll admit that I prefer to have a semi when I'm in the locker room, just for ego sake. I don't want to have a hard-on, cause I'm not interested in that.
Actually, I think it's kinda tough to determine what a semi is anyway, since for most guys (from what I've read), the soft size varies tremendously.
Had a friend in high school who was a major shower, but when he got hard, he just got hard--little to now growth. Mine, on the other hand, doubles.
