Secondly, the male talent in their straight porn are leagues below the guys in the West. We now actually demand the guys are attractive too, mediocre middle aged men won't fly with us. We left that shit back in the 80s.
Just in case it's not obvious, this is very much by design. The guys are not "mediocre", they are intentionally ugly or aged, often exceedingly so.
In fact, up until a decade ago, it was extremely difficult to get a straight gig if you're a conventionally handsome guy (now being just as difficult as for the next guy, which is still very). Having a big dick has also been a disadvantage, unless for the specific niche productions or gay video of course. This is the reason why there's such an abundance of straight sex produced by gay video companies.
