“勾引”是個相對比較長的過程，算個Project。你得有計劃，有策略，控製時間和成本，畫個PERT圖啥的來優化，反正比較serious。比如象泥泥計劃的，過年吃餃子後，昏天黑地裏，軟音樂漸起，金蟾齧鎖，玉虎牽絲。。。這是Projected的“勾引”。:DDDDD
“Turn on”就不同了，可能是Project的結果，但更可能是既興而為。興之所至，來如風雨挾雷電，去如春夢了無痕；可以隨時隨地，不拘42式；可以隨配合菜，豐儉由人。。。這叫啥？
不知道中文裏有沒有這個詞“休閑性愛”？
英文裏倒是有個Casual Sex（見下麵解釋），但好象完全沒有“休閑”的意思。如果正本清源，該詞是被嚴重歪曲和忽略了。:DDDDDDD
Casual sex refers to certain types of sexual activity outside the context of a romantic relationship. The term is not always used consistently: some use it to refer to any extramarital sex, some use it to refer to sex in a casual relationship, whereas others reserve its use for one-time encounters, promiscuity, or to refer to sex in the absence of emotional attachment or love.
