Couples use the word in private; doctors and sex educators use it in a calm, teaching way. It is not a swear word, but it is an adult, private topic, so you would not drop it into light classroom chat.

Couples use the word in private;情侶會私下用這個字； doctors and sex educators use it醫生和性教育者也會用它 in a calm, teaching way.用平靜、教學的方式。It is not a swear word,它不是髒話， but it is an adult, private topic,但它是成人、私人的話題， so you would not drop it into light classroom chat.所以你不會在輕鬆的課堂聊天裡隨口提到它。

Though actually, people sometimes joke that a long warm-up before “the real thing” is foreplay — twenty minutes of small talk before a meeting, for example — but that stretch can sound crude, and it is not the main meaning.
