When forcing someone is used to make sure sex happens, they call that rape and list it as a crime in the legal code. In spite of what a lot of people think, the definition of rape hinges on the detail of consent, not how rough it was. Some acts of rape do not look very different from consensual sex in terms of mechanics, but it is a loathsome experience for the person who did not want this.

I think that principle generalizes pretty well. There are better ways to deal with people like this than forcing them to do something and insisting it is for their own good.

Friendship that is not based upon real respect is not genuine friendship.
