还是中文精致些，爱，爱情，情，情欲，欲，它们自己或者相互的组合变化出许多不同。
爱是更广义的，充满感情的，或者无私的。
情是感情，喜怒哀乐憎之类的。
而欲，更广义意义上的，则是似乎无穷无尽陪伴我们一生的。或者因此我们而成为人的。
孔子说过三种需要提防的欲：年青时候，气血轻浮，容易好色（情欲）；中年时候，气血旺盛，容易暴躁（权欲？控制欲？）；老年时，气血衰竭，容易贪财（贪欲）。
情加上欲，情欲，就多了一些18+敏感词的嫌疑。
而爱遇上情，爱情，是渴望互相占有的，被承认的。

中医讲气血，科学告诉我们是荷尔蒙激素小分子。
如果没有荷尔蒙和雌雄性激素，爱情这东西还会存在吗？
爱神之箭上一定沾满了荷尔蒙。所以射到谁就是谁，人生和谁初见就爱上谁，就这么简单。
所以牛郎碰上了织女。许仙遇上了白蛇。董永偷看七仙女洗澡。
要是当初被谁插了队，也就逮谁就是谁了。

一日和同事聊起电视剧和电影，越是不真实的我们越喜欢看，因为来源生活和远于生活。
那些美丽帅气的男女主角可以一遍又一遍地演绎那些白雪公主富贵王子，落难书生白富美，误会纠结巧合等种种套路。
百演不厌和百看不厌。爱情永远是这套路中的主线。
也许，这爱情可能是造物主给我们下的一个套，一个甜蜜的圈套。
一朝套进去了，用剩下的一些残余的气血或者荷尔蒙繁衍生息了，就用大半辈子去围着柴米油盐孩子慢慢磨。
得闲时，看看脑残爱情剧，和自己并不相干的讪讪地笑笑。

English version

I intended to make the post a bilingual version, and found out that it's hard to tell deliberate differences without referring to Chinese origins.
For the three Chinese symbols: 爱 (Love), 情 (Emotion) and Desire (欲), either of them stands as a single word, and two of them combined lead to related but different words: 爱情 (romance), 情欲 (lust/erogeneity). Please correct me if you have better translations for these Chinese words.
Love is more generic, could be fondness of anything/anyone, nature, kids, or one's hometown.
Emotion, as it stands for, reflects our emotional status: joy, angry, sad, happy, and hate etc.
Coming to desire, it often accompanies us throughout, making us as human being.

Confucius once described a few desires one should guard against, regarding one's age and vital energy (气血, sounds like energy bar in game):
when one is young and his vital energy is not fully settled, he might be susceptible to the desire of sex; getting into middle age with loaded energy, he could be easily irritated to fight, probably due to desires of power and authorities; once becoming older with weak energy, man could be prone to the desires of wealth.

The two Chinese words "Emotion" (情) and "Desire" (欲) will together form a word of "lust/erogeneity" (情欲), making people think of a typical confirmation question that you are at least 18 year old, before entering some sensitive website...
The Chinese "Love" (爱) plus "Emotion" (情) is a special form of love: "Romance" (爱情), the intimate attractions between man and woman.

According to modern science, the so-called "vital energy & blood" in Chinese medicine probably correspond to sex hormones (estrogen and androgen) consisting of chemical molecules.

If without these hormones, whether these love romances would ever exist?
The arrows of Cupid should have been treated with plenty of such hormones. Whoever shot by his arrows, will fall into uncontrollable loves with any first met stranger.
This will perfectly explain quite a few classical Chinese love romances. Gosh, I won't risk my shabby English to repeat the full stories, just feel how lucky we are to have almighty wiki:
- The Weaver Girl and the Cowherd "织女和牛郎" (https://en.wikipedia.org/wiki/The_Weaver_Girl_and_the_Cowherd) : the traditional Chinese valentine's day was basically made from the yearly reunion of this couple.
- A beautiful white-snake spirit and a young man "白蛇和许仙" (https://en.wikipedia.org/wiki/Legend_of_the_White_Snake).
- The seventh daughter of Jade Emperor and a mortal "七仙女和董永" (https://en.wikipedia.org/wiki/Tian_Xian_Pei): a note, the guy stole her special feather coat, while she was taking a bath; yup, and he was peeping her in the bath as well.

I was once chatting with my co-workers about TV series and movies, the more unrealistic/insane they are, the more cheerfully we watching. It's probably because they are far away from the actual daily life, although claimed to be originated from real life. These beautiful actors and actresses could together produce numerous versions of love stories with a few common stereotypes (you name them since difficult for me to translate :P ).
Nevertheless, we never get bored of watching the shows, as the attractive love romance is forever in it.

Maybe, the love romance is just a trap setup by God, a sweet trap though.
Once trapped, you'll reproduce with remaining active hormones (or "vital energy"), then you've done. You'll spend the rest of the life to raise kids and pay endless utilities/bills.
During leisure time, you may continue watching some of the enjoyable love romances, smiling or chuckling.
