I think she was probably pressured into a lot of degrading stuff early in her career, or unethical things like casting couch but for photoshoots. There are also rumors that she was or is a very high end escort (these are dubious though). The industry was pretty rife with this kind of behavior toward new talent before metoo and onlyfans. Now that she's financially independent, she may have a different relationship with sex and dating as a result of those events, as well as being a softcore porn star for her entire adult life. She could very well be celibate, or go very long stretches between partners. I wouldn't be surprised if she just had a small roster of trusted guys in various cities who have a proven track record of meeting her needs and also keeping their mouth shut, and she just gives one a call every now and then when she feels like it.
Or maybe she just doesn't sleep with guys anymore, which is what she claims. But it's important to realize that this could very well be a PR move from her, or a way to just avoid the conversations about it in general. While she does seem like a very open person, she's not obligated to be 100% truthful to her fans. She does have boundaries, as we know from the fact that she's spent 15 years in the sex industry and has never done PIV content.
