1. errr no! but that's my opinion ..
2. why would a 14 year old want to sleep naked with their father?
Yes
Im 15 and i do
no
you shouldn't sleep with your dad. That is VERY wrong! if your dad wants to sleep with you that's child abuse.
People sleep naked of all ages so of course you can. Just wear something when you need to go to the toilet.
There's no reason not to if they are most comfortable like that.
For a mother, it is assuredly not okay. For a father, it is questionable and just not necessary. But, different people have different mores.
Perfectly ok
Yea
As long as it's just going to sleep on his bed, and not that other kind of sleeping with her father, it shouldn't be a big deal at all.
Not legally.
No. It is illegal. The minor child can not sleep with an unrelated 19 year old adult.
