No as long as they are awesome in every other way which they would have to be because they would be my children
Not at all, I would be proud that they are being themselves.
No, I'm not a total idiot.
upset, no - but it would make me more worried for them probably
I would be, but only because I'd realize how hard their life was going to be.
I have to be honest I would respect my child's decisions but their intimacy would have to be out my field of view.
