You are absolutely right, no one is to be forced to release information about their sexual encounters against their will. The point I’m making is for those who are interested in “honest” committed relationships.
As you said, relationships are based on negotiations, before getting involved it’s important to ask these questions about sex. I don’t believe people change overnight. Asking questions about one’s view on sex and other areas is a great way to know who you are dealing with; if someone believes in sexual liberation while single, they will hardly change with commitment.
We aren't judging those people for their choices, just making sure if we want to get in a relationship with them, their views match ours.
