“Is sex dirty? Only if it’s done right.”
Some people have a problem with describing sex as dirty, since it can suggest that sex is a negative, degrading, or morally corrupt thing. I don’t believe sex is dirty in the “morally unclean, corrupt, shameful” definition.
But I like the word dirty when used playfully, and I so I choose to use it in that way. When I say dirty I mean sexy, lustful, hot, unrestrained, shameless, passionate, horny, arousing, hard, wet, etc…
