If "God made sex for procreation"...?

[Xiao Gui]

Why are some people born infertile?
Why do some people have trouble conceiving?
Why do some people lose every pregnancy they do achieve?
Why do some people have to try again and again for YEARS before they successfully conceive?

Isn't it possible God intended sex for many things (love, bonding, relationships, intimacy), procreation being just one of them?

 

[drumbum]

I was always taught he made it for procreation and recreation.
