This is my husband wearing this jockstrap! He loves it and so do I! I own a pair, but wanted to share my husband's POV. The 'inside cup' holds your junk in place and gives you that bulge you are looking for! The jockstrap's fit is snug and have freedom of movement without being restrictive. My husband and I have been fans of Cellblock 13 for quite sometime and the Interceptor Jockstrap is one of their best...yet!
