I don't think so.
If you open your house up to the public as a b&b then it would be breaking descrimination laws to ban people because they're gay.
In my eyes there's no difference between this & the "No Dogs, No blacks, No Irish" signs that occasional b&bs sported in the 50s.
Except nowadays there are laws in place to stop this.
