I'm gay, but I don't think I would ever adopt children. I think even if I were married to a woman, that adoptions do generally have too many issues and problems.

if I ever have children it will be because I got a surrogate mother, or I had kids created from a combo of my dna and some guys dna. (possible)

I think people often aren't really able to be truly close to kids that are not biologically related, though they may try. I also think it is best, if kids must be adopted because something happened to the parents, for them to be adopted by biological relatives.
