I must say, ever since you started having regular intercourse, your mind has lost its keen edge. You should reflect on that.

我不得不说 自从你开始定期交媾之后 你的脑子就没那么好使了 你应该采取点儿措施的。

You've been on and off with this woman for seven years and engaged for one year. One has to wonder if there's a problem. Are you having satisfactory intercourse?

你跟这个女人分分合合七年了，然后也订婚一年了。让人不禁疑惑：你们俩性生活还行吗？

Two people can go on having sexual intercourse from habit in just the same way as they grow hungry at the hour they're accustomed to have their meals.

两个人可以习惯性地继续性交， 就像他们在习惯吃饭的时间变得饥饿一样。
