Hi, Does anyone knows, which one is smaller and don't make a bulge in the crotch? CB2000 or CB3000? Frenum is better but needs a piercing in order to stay in place. Here, a person getting his/her genitials pierced is not tolerated. So, i won't be able to use the Frenum. But... IS there a chastity tube smiliar to Frenum chastity http://www.centurianonline.com/eshop/10Browse.asp but which doesn't need to be pierced.. ???
