My public school taught a simple way to have fun without values or emotional ties, just enjoying physical pleasure (although the pleasure can be found with the values and emotional ties too), and as a bonus we get one in six with this "oopsie".
I got into a verbal altercation with a nurse a few days before I got married over the law in Michigan that tells them you have to get a lecture on AIDS before you get your marriage license. I told her it was stupid to make a guy getting married sit through this and she went off on me -
“Don’t you worry about the AIDS epidemic?!?”
“nope, I’m getting married next week and I have no concern whatsoever about it”
“How can you say that? millions of people will die from this!!”
I told her they should have this little talk before kids get their drivers licenses, not someone who is about to swear themselves to a partner for the rest of their lives. I guess she must have been a jilted lover or something, but I still remember her look of disgust with me when I just laughed her concern off.
