What Size?

The first time I went to a chemist to buy condoms, I was served by a beautiful young woman. She asked what size I wanted and I said I wasn't sure. So she asked how big I was and I said, ‘Compared to what?’

She held up one finger and asked if I was that big. I said, ‘I'm bigger than that.’

Then she held up two fingers and asked if I was that big. I said, ‘I'm bigger than that.’

Then she held up three fingers and asked if I was that big. I said, ‘I'm about that big.’

She put the three fingers in her mouth and said, ‘You're a medium.’

Hahahaha
