No. I was a bit like you, op, in that I never had a strong biological urge to have kids and could always see the downsides as well as (often more clearly than) the positives. So DH and I focused on our careers, travel, study etc, did all the other things we wanted to do, until at last as I hit my late 30s they started to pale a little (been there, done that), and we realised we had to actually make a decision whether to try for a baby. We did, for all sorts of rational and sentimental reasons, and now our DS is here, OH MY GOD I am soooooooo glad we did!
I was all prepared to 'get through' the baby years, to be miserable at home and missing work/ city breaks / nights out, but I have loved him and being a mother from day one. I found a whole side of myself that I had no idea was there. And it makes my blood run cold to think I might have missed out on all the sheer, heart-expanding joy of him just because I didn't know how good it could be. I think parents always tend to emphasise the negatives - the jokes that you'll never go out again, get a shower by yourself, travel, lie in the morning (ok, the last one might be true), but skip over all the amazing bits. It's very British, I suppose!
Of course, everyone's experience is different but just know it can be wonderful. I am glad we waited though - do all the things that you think kids might get in the way of first! And ideally get a good financial footing. We have a cleaner, can afford regular babysitting, still to travel etc which makes life a lot easier.
Final thought: if you're thinking about this so hard, maybe you're not as in the fence as you think?
