There's nothing wrong with having sex that involves love (whether romantic or friendship) and intimacy and trust. In fact I would argue, without that, sex can be unsafe, either physically or emotionally. I don't think this is a good idea. Not because I'm an awful sex negative puritan (quite the opposite), but because sex is a form of vulnerability and if you don't behave as though it is, either you or your sexual partner can get hurt.

I would highly suggest seeing a therapist to work through "Good Yael" issues, rather than committing a form of self harm because you want to DESTROY a part of yourself.

It's not that casual sex is necessarily bad, but if you want to essentially USE someone, and not care about them, and use them as a robot to order around - don't do that to a random vanilla person. Find someone who wants to be a sub on fetlife if that's what you want, because they'll love it.

I don't think that you should necessarily try and destroy the part of yourself that cares about other people's feelings and wants to make them be happy, but rather find healthy boundaries where you can mutually be happy, and communicate if you're not happy. Because if someone gets pissed because you set boundaries, then you shouldn't be with them anyway.
