hmm at least speaking as a male who watches JAV - I haven't seen any AMWF or AMBF, so it's certainly possible I'd change my mind, but I'm watching for the girls, if I want to watch a WF or BF, I can just dig into American/European porn. The Asian male vs. them doesn't hold any plus at all for me, and it's doubtful a WF as pretty as, say, Little Caprice is going to pop up in JAV.
Not awkward, just unnecessary (personally).
On the other hand, if they did something like one of the elder caretaker or forbidden stepfather things with a WF, I might get into that. Could be a twist, poor guy nabs himself a white girl only to have his dad snatch her up.
