I used to not care much, besides not having any interest in BL main couples (not that I read a lot of dedicated romance stuff), at least with books (not that there was a lot of BL or GL in mainstream books).
With manga (and anime), I've always sort of had a thing for GB in general (with the occasional GB-GL). More recently, I've really taken a liking to GL manga (GB or not). On the off-brand side of manga and anime, GL with extra equipment has been fascinating for a long time.
Now, since I came to SH, I've sort of shifted to mostly GL, with only a few stories with MxF pairings I still read.
Recently, I have a hard time even getting interested in stories with male protagonists, while GL is almost an auto-include on my ever-growing list of stuff to read one day.
Still very much no interest in BL as main couples, though I don't mind them for supporting cast (gotta find a place for all the males anyway).
