This enthusiastic consent is an interesting idea. I don't see it as remotely practical. Rates of sex are declining across our population in general. It's especially worse among younger generations and I can see why the culture has created it.
1. Tinder- It's basically a way for people to hook up for sex but there is very little attempt to create a relationship. It circumvents the natural biology we have developed and the social norms of dating to find a mate. In the old days women would have sex with men they found worthy of giving it up to. Now it's a put out or get shut out. Don't have sex and the men will just move on. The competition of dating has broken down. I think that really hurts women over men.
2. Enthusiast consent- what do you do with sexual disorders, especially in women? There is plenty of scientific data from women who lack an interest or desire for sex, but if they begin to actually have sex they become aroused and enjoy it. They are never going to enthusiastically consent but they have no regret, distress, etc about their sexual encounter.
3. Married people- there are a ton of people with mismatched sex drives. There is a ton of coercion or bargaining. "You get the garage cleaned and I'll make it worth your while". Not enthusiastic. "I'm tired" transforms into good sex for both after some coercion. Under the enthusiastic consent idea, there is a ton of raping going on.

4. Alcohol- I'm assaulting my wife and shes assaulting me, ALL THE TIME!
5. Finally the threat of retribution- look rape is rape. When someone says no it means no. However, the me too movement has done a lot of harm. People cant be destroyed 20+ years later for things that are simply alleged or if they felt uncomfortable about something. We have to have a better process. I don't know what that is but we have to have some difficult conversations to sort it out as a society.
