On that very subject...
A man goes to see the doctor, expecting a male doctor, he became very withdrawn at the female doctor. He stammered that he had an issue downstairs. The female doctor reassured him that she's been a GP for 20 years and nothing could possibly alarm her. He felt a bit better so he continued that he had a problem with his penis. She said 'well ok, remove your lower clothing and I'll have a look at it'. The man nervously disrobed and show his penis to her. The doctor was stifling her laughter as it was the smallest one that she had ever seen, it was minute. The man asked if she was laughing at him. She composed herself and said 'No, not at all but what seems to be the problem?'
The man replied 'It's swollen!'
