It's really a bit cold, and someone is peeking.

It's really a bit cold, and there are also people who might watch. A man went to see his family doctor and asked, 'Doctor, I'm going to get married, but it's our first time for both my girlfriend and me. Can you tell us what to do?' The doctor had watched the man grow up, and hearing this question made him a bit uncomfortable, so he looked outside for a moment and then said, 'Look over there, do you see the two dogs in the park? Do you see what they're doing? Go home and do the same, and you can't go wrong.' Two months later, when they met again, the doctor asked, 'How is your sex life?' The man replied, 'Very good, just that doing it in the park is really a bit cold, and there are also people who might watch.'
