It depends. If we're talking about av idols veterans/Girls like Maria Ozawa, sora Aoi, and yui hatano then it definitely worth the High price if they're still young and at their peak. Nowadays, they're still naturally good looking with makeup along with their middle age fat. However, they're more used up now even if they're still tight and expressive with their fake moans. It's nicer to get them when they still possess some specks of innocence and shyness. Nowadays, they're pro that's hard to really satisfy and enjoy even if you have the chance. It's still nice to have the real thing to satisfy your fantasy, but don't expect too much or you'll be disappointed. I might prefer someone newer and not someone that knew and probably done everything already in their career onscreen and in private. A lot of av idols aren't hot or feminine before their av or gravure debut. There's a trend of av idols losing their virginity to some old guy before they became hot. Good makeup and diet can make a lot of girls look beautiful. Nose job, eye enlargement, and implants helps too.But are they worth the exorbital price tag ?
Besides av idols, There are also a lot of high class courtesans that are differ from your everyday hooker serving commoners off the street. Unlike av idols, they don't get shame because no one would guess they're prostitiutes. However, most of them are probably reserved for the wealthy in their secret clubs.
