Not sure if this is relevant or not.

My best friend is gay and he lives with his partner. he is also my childrens godparents.. We only see them once or a twice a year but I do not point out the fact he has a male partner..

When Ds8 asked if M was S's boyfriend I just said yes, Of course he giggled about it but then asked a few questions and now is fine.

I just don't even make an issue as I want my children to not even bat an eye lid at same sex relationships.
