Good one @WaitRose.
I occasionally responded "as far as I know you can't get pregnant from swallowing, so no time soon!" but I mostly used to deflect those questions. My husband used to say "when we can find a decent used one at a good price" which really confused a few people.
We are both ultra-private, and very self-contained as a couple. We talk to each other a lot but not really to anyone else at all. We both have families which are uncomplicated but who we find very difficult. We didn't want to tell anyone, and I initially refused the fitness program at our clinic because I didn't want anyone to know anything about me and that I was having fertility treatment.
