Same here- DH and I can have kids (as far as we know), but have never attempted pregnancy. We both intend on adopting from China, and we plan on a pretty big family as well (3-ish... but one step at a time, right?
) I used to let everyone know that my intentions to adopt had NOTHING to do with infertility, but finally I'm wise enough to not care. My preemptive going about shaking off my supposed infertility could actually do more harm than good in hurting the feelings of those who desperately want a bio child. So, I let people assume what they want to assume, and will let them know if they ask.
