I always used to fantasize about this scenario back when I was a babydyke. I totally would have been up for trying it if the woman I married had been up for it too (as it was, she was barely on board with one
of us ttc at the time when we first were).
We definitely would have done the "my eggs in your uterus" thing if it weren't for the fact that it's so darn expensive (unless you have fertility issues already dictating IVF with donor eggs). And the increased risk of twins. We know two couples that did it (both have twins), and while one couple was able to have it paid for by insurance (the gestating mom had premature ovarian failure), the other couple said it cost $25,000.
When dw was early in the current pregnancy and I got my period . . . things were not very friendly in our sweet little home for a few days. I can only imagine how we would have managed our raging emotions had we both been subject to pregnancy hormones at the same time (that said, some people are not particularly bothered by the hormones of pregnancy, dw and simply belong to the other category of pregnant people).
I also don't know how we would have figured out who got to sleep-in in the mornings (clearly this is only an issue for families with older children already . . . or demanding pets, I suppose). When I was pregnant, I almost always got to sleep in. And I've returned the favor for dw's pregnancy (despite nursing a toddler all night, I still
know that she's probably more tired than I am). And I can only imagine the battles we would have had over who got to take a nap in the afternoons . . . so I guess it probably is for the best that I didn't marry someone who wanted to do the "let's both get pregnant at the same time and have lesbian twins" thing. But I still fantasize about what could have been from time to time.
Congrats to Cat and Jennifer Cora (I must admit I have NO IDEA who these people are)!
