I heard from all the guys on campus that the clinic was having some sorta sperm drive. I was skeptical at first but I was handed a flyer by a med student and told me I was perfect fore the study. I had never done anything like that so coming from a small town I was a bit excited and nervous at the same time. In walks a doctor and hands me a specimen cup and points to a table with all kinds of lotions and some white thing he said was for my butt. After getting my bone up I decided to try the prostate simulator, and wow! I had never felt an orgasm so amazing. I felt the inside of my ball sack literally tingle like never before. I wonder what other studies I can try at the clinic.
