i really agree with what bob said. having a child is a really big responsibility and it's someone who you need to take care of for many years, so before having a child you really have to think about it a lot and make sure to make the right decision. i do hope that one day Japan will be more accepting of same-sex couples and if you both decide to have a child, that it is possible. i wish only the best for you both!
I hope one day soon it becomes acceptable in your society for same sex marriage and same sex families. After all love is love and how can that be wrong . 💙💙
