Even av actors themselves hope for more male talents to join the industry because the industry is seriously lacking men. Seriously, being a pornstar isn't as cool as people think. It's a low paying job even for regular dudes. Besides the backlash from your career choice(try keeping your occupation a secret) and tiring sex, you probably won't even get to have sex with your dream girl. They need guys to perform with all sort of girls in the industry and some are quite disturbing too.
Shimiken seems to earn enough money to have several cars. He has an Audi R8 among them. He's probably an exception and he said that he works a lot, he even has to eat on the sets because he doesn't have enough time between the shootings. I agree that the backlash isn't something easy to deal with.
I agree that you don't always fuck beautiful girls. But, compared to american pron with all duck lips and crack heads, I didn't see very ugly girls in JAV. Even the fat girls, their faces are okay.
I tried to pick among amateur in uncensored :
I don't find her attractive at all, but I didn't have a 'what the hell ?" reaction unlike this one (phoenix marie)
