I am hoping that someone can advise me/share their experience of this. My DSS came out in April after a broken relationship he is 17 now and says he knew from Year 8 that he was gay. He is in a new relationship and has told my son that he doesn't want to bring his boyfriend round to the house, we would be happy for him to bring him round, but we haven't yet told his 10 year old brother that he is gay.
Background is that both my DSS's have been raised as Catholics and the younger one attends a Catholic school where normal sexuality hasn't even been dealt with yet, younger brother is about to go into Year 6 and they don't teach about homosexuality at all.
Should we tell him? It might make it easier for his brother to feel he can bring his friend to meet us, but it might also make him think less of him given the teaching at his school and also what has no doubt been said in the playground 
Any thoughts welcome
