In this day when people seem to want to wait 30+ years to bring up something that you did when you were in high school, I think it might be a bright idea to create a sexual consent form.
This form should be a free phone app and have consent and details spelled out by both parties. (Or all parties if you’re into that sort of thing.)
These consent forms should be installed on everyone’s phone. Sex education class should emphasize that these forms need to be used each and every time, and signing one is the same as signing a legally binding contract. Each form would automatically upload to the cloud.
A public service campaign could make the public as aware of these forms and the need to use them as they are that cigarettes are bad for them.
I think that would do more to prevent teenage and unwanted pregnancies than telling your partner you’re going to name your first child “Wet Tile Floor”.
