I prefer perfectly perky natural breasts, that are undetectably the same size & shape, positioned slightly high on her chest, also that they are also less than D cups.
Having said that, if it is a woman's choice to go into being naked for her profession & she has less than perfect breasts, I prefer that she get a high quality boob job. Living in Vegas, I have seen many fake breasts.... still my favorite style of boob job, is the cuts under the breasts in the crease, with a shaped factory sealed bag. With the FDA banning of Silicon Gels in boob jobs, most of the Doctor Saline inflated boob jobs look worse than what the woman had before she had the surgery. There is nothing worse than a bad boob job. With the cuts under the breasts & a factory sealed shaped implant, the Doctor can get the shape, position & size perfect. The major downside is the 2 huge scars under her breasts..... but I think everyone already knew they were fake, before she took off her top & she can always get ***** reduction surgery later.
Lastly, I should state that I am not really a boob man, I'm more of a ass guy, & a hot woman, will always be hot to me regardless of her breast size. In real life, I have never broken up with a woman because she had less than perfect breasts(real or fake)..... but I have refused to get lapdances from strippers with ugly breasts.
