Most likely he can find one. You can find a lot of things.

"Should"? I think if it happens in the course of things, that may be OK. If it is hidden, the child will probably pick that up. If it is made a point of, the child will probably pick that up too -- and be confused about why.

I agree that society is in many respects not healthy in its attitude towards sex. I am not sure his way will be that much better.

Some things to consider...
