I've been clamping for about 3 weeks now. I've been sick with a fever for 3 or 4 days now. Since then I've had trouble sustaining an erection, and my pre-workout girth is down about 1/8 inch. Its pretty crappy b/c i have such little girth to begin with. You guys think this is because i'm sick with a fever and sore throat, or the past 3 or 4 days of 20 mins x 2 sets and 20 mins x 3 sets of clamping was too much ?
