interesting question imo
I have a gay nanny friend - she normally mentions it at 2nd interview, some famillies go back to agency and show/share their disgust, others are happy she was honest and offered her the job.
it shouldnt make a difference what sexuality the au pair/nanny is ,as long as loved and cared for the children
but you wouldnt want either gay or straight canoodling when looking after your children
would anyone object to a gay male one?
