All 3 of ours came out at about this sort of age.
We didn’t ask. Looking back it wasn’t a huge surprise.
We could have asked when some signposts were up but we didn’t - not a conscious decision either way.
If we had our time again I would do as we did - ie not ask. I think it better to provide a safe and secure environment - so that one’s children can tell you such things and know that they will still be accepted and loved.
I think we had a welcoming and accepting house, all 3 had friends round and it was generally a full house.
All 3 brought round various b+gfs round fairly early on. One or two had been treated appallingly by their parents.
All 3 are out publically - but in someways it’s not an event now. Not hidden, not shouted from the rooftops.
At the time - 15-20 years ago there wasn’t the knowledge about non straight children having mh problems or taking their own lives. Fortunately we didn’t have this sort of thing to tear our family apart.
Coming out - whether it’s the person telling family, friends etc or whether it’s parents asking is hard. The person stating matters, the parent asking doesn’t know the answer or more importantly the reaction to the answer.
It’s not something that has a half way answer. Its either a year a no or a lie.
So - best to provide an accepting, secure, open and supportive environment without sit down questioning sessions or fears.
For us, as parents, the hardest thing was telling my parents. (With children’s permission and knowledge) We felt it could go either way and we (DW and me) were quite prepared to walk and go NC. Fortunately it went ok.
I know others think - they’re the parents with 3 gay children - they must have done something wrong. Others have come to us for advice about their concerns for their own gay children. To the first group - sod em. To the second ‘how can I help?’
All the best.
