You can't be politically correct. It's for small-minded people who are afraid of the shit inside themselves, who try to make themselves feel better by making useless, meaningless efforts to verbally balance the scales. Language exists, use it. All of it. Even the dripping, black words that have no shred of goodness in them.
Every word has a use.
If you think you might be politically correct, get help. Sex is great and fun and it doesn't have to be deep and emotional, although sometimes it is better when it is. Sex is not love, but love requires sex. Sex is not bad. Don't carry signs and march.
