I almost forgotten my experience.
I went to 家計會 before I got married. That was about 15 years ago. All the doctors are women. The lady doctos was about 35 (I was only 25). She sound like from Mainland china who cannot practise in HK and therefore happy to work at 家計會 for lower pay.
She gave me a test tube to take my semen sample myself. I went to the other private room with lots of adult magazines. After I done, I rang the bell and she came back. The nurse took the sample and she thenasked me to take of my pants and checked my testis (with gloves on her hands) and my foreskins. She needed to check if my testis are soft. I suddenly got hard and that was embarrassing. She smiled and comforted me that it was very normal.Most men would have this reactions. She said if it is ok if she check the other side of testis.
I thought she would measure my length but she didn't. Before we finished, she asked me if I have any quesitons. I was brave to aske her if my size is ok? She said most chinese man are at 4 - 7 inches. Clinically, 3.5 inches is long enough to make love, but of course, the longer the easier. I then asked her what was the record she has seen. She smiled and said many men have asked her this question. She said is about 8-9 inches, but the man is a black american.
