This is my first post here so apologises if this is in the wrong place.
DS is 16 and so is his best friend. They've been friends since year 7 and they've just finished year 11. His friend is gay. He's always came round here and had tea and played on the Xbox with DS.
Today, he came round and they were playing on the Xbox. I went upstairs to put some washing away and I noticed DS and his friend kissing (The door was open).
I'll obviously be fine if he's gay or in a relationship with his friend but I'm not sure he knows ill be fine with it (he knows his dad is very homophobic).
I'm now wondering if I should tell DS what I saw or if I should wait for DS to start the conversation? Any advice will be appreciated
