I walked in on my 7 year old son searching YouTube for "boy parts". We had a calm conversation but he couldn't really explain (to me) why he wants to see other males private parts. There has been no inappropriate behavior or actions towards him. But what I do know is he is and has always been more feminine? His interests have always been what a little girl would like...movies, toys, clothes, make up etc. For a while I was thinking he might have more of a gender identity problem but now I'm wondering if he's gay. That sounds harsh way of explaining so I hope this makes sense.
However, regardless is it normal to have such curiosity and it be harmless?
