Like I said, regulate it. 23 and up. Same for adult entertainment. It'll shift the culture over time as well. If you think the abortion thing went badly, wait till you tell people they can't have sex anymore.
Goes without saying, but yes. Humanity had all this figured out and then corrupters are the ones that ruined sex, shamed everyone with mind games, and then used it to control others. If you want to take away the power of it being used for corruption you have to shift people's perspectives. Get it out in the open and regulate it. Then nobody can use it as leverage.
