When you think about it we actors are kind of prostitutes. We get paid to feign attraction and love. Other people are paying to watch us kissing someone touching someone doing things people in a normal monogamous relationship would never do with anyone who's not their partner. It's really kind of gross.
There is no more lively sensation than that of pain its impressions are certain and dependable they never deceive as may those of the pleasure women perpetually feign and almost never experience.
