Toria that sounds a wonderful experience and you tell the tale of it very nicely and matter-of-factly.
I think that is sometimes the issue with the 'smug' thing - the matter of tone. Obviously there should be absolutely NOTHING wrong (and everything right) with a woman saying, 'you know what, it was a good/wonderful/fine experience for me, no pain relief, no tearing etc... that's just the way it was for me and I know it's not that way for everyone. I wish it were.'
I think (or suspect?) that the 'attitude' that upsets people/makes them feel like failures is an entirely different tone which IS either smug - 'it was so easy, I did everything brilliantly, I don't know what people are making a fuss about' - or alternatively a kind of hectoring, "You MUST do hypnobirthing/yoga/listen to whale music, you won't need any of that dastardly pain relief if you just think beautiful thoughts..."
I think it's absolutely wonderful if other women feel able to say they had a good birth experience as that sort of thing can only help.
I've only met one woman in RL who managed to tell me about her good birth experience in a lovely, positive, non-hectoring way. I've met quite a few more of the smug/hectoring variety.
I thinkk if we all just accepted that our bodies and our babies are all different, and thank GOD for modern medicine that can save women's and baies lives and - heaven forfend - even make the experience less painful/chaotic for them, we would all be able to get on with giving birth however we are best able.
I also think, sadly, that the age-old refrain that it isn't a contest and that there are NO MEDALS for giving birth however the hell you end up doing it... isn't getting through.
I fudge the truth (OK, I lie) about my ELCS because I don't want to tell most people in RL that I was so phobic about vaginal birth that I just couldn't countenance it... silly labels like 'too posh to push' are bandied around which are frankly just another way to demean women and make them feel like they should put up with whatever Mother Nature can throw at them. Thank God it's the 21st century in a 1st world country and we do have choices about many aspects of this.
