I unsurprisingly have absolutely no problem with including the BL in the listings. Same goes for the rarer girl x girl stuff aimed at chaps (and the equally rare but lovely female-orientated girl x girl manga too which sneaks into the US from time to time), along with 18+ stuff in general when it isn't too obscene from the covers. I think most book publishers keep it tasteful where possible in the US anyway.
Ayase: I don't like to watch real porn of any orientation, more because I don't find real people (strangers at that) worthy of idolisation in the same way that 2D representations are, and also because I don't find it interesting unless there's a story building up with more to it than the usual plotlines of adult videos. I think that written fanfiction is similarly dominated by content aimed at girls on most websites, and indeed at doujin events there always seem to be a lot more fan novels (as opposed to comics) in the BL section than in the section populated by male creators.
There's a big divide in BL in terms of stuff which is very much aimed at women and stuff which most gay men would realistically enjoy, though, so I think females liking actual porn tailored towards the taste of homosexual men would be fairly unusual even amongst people who are into the whole real people thing.
However, I have no qualms with gentle real world boy x boy teasing. This pair of performers,
singing as a silly modern take on a certain famously homosexual historical pairing, does a lovely job of playing to their audience and they continue the act in interviews as well. It helps that Ranmaru is so pretty >_>
