For the most part, a turn off, but it really depends on the woman. It worked for Abella Anderson, but not for Mia Malkova for instance, at least boob job wise IMO
Most of these lovely ladies do not need plastic surgery or enhancements. It should be a crime especially if it's work done to the face.
Mia Malkova is still great but not as before. Lana Rhoades is still great but I think if she was natural than the thrill of watching her would be even more.
There are various catastrophes out there that are best left unacknowledged though.
