Why are all these reasons about sex. I dont get it at all. Sex has never for one second entered into my decision making process about having kids and honestly I think it is kind of a poor reason. If I felt my husband was selfish enough to not want kids because he might get less sex Id say screw him, thats what internet porn is for (just joking) There are so many more intellegent reasons for not having kids though, and for having them. Also you will stay have time for sex if you have kids, afterall most people have siblings. What about hte money, the time, the fact the kid will come first in everything. I think you both need to think about you want picture your life with a child and without a child and discuss it at length. Borrowing a child is a good idea but remember it wont be the same thing at all.
