Numero Uno for me has always been Southern Brooke.
Otherwise I have always appreciated and respected models who chose or choose not to do hardcore, even with their partner. Going hardcore should not dictate popularity, and there have been OCSMs on here who have commented that they'd potentially lose fans if they made the switch. For those that go hardcore with their partner exclusively, I could never fault them for making that decision. They're sharing their sexual experiences with us and if they enjoy what they do, that's what counts the most.
Andi Land's comment makes a lot of sense. It's terrible to think that such a thing as personal as intimate moments could be used nefariously but yeah Revenge Porn is a niche too sadly.
