I've heard that pumping works...........but it takes YEARS of fairly consistent work to see any real meaurable increase. I guess I'd rather do that than walk around with weights tied around my tip.......I dunno. I haven't felt the need to do it cause the women I've been with have enjoyed me. But there are women out there that REQUIRE no less than 8 inches........whaddya gonna do then if you get with a woman you really like but she's been having sex regularly her whole life with really big guys??.....
