There's some massive lunatic guy who claims to have some level of degree in flowers and freud or something medical knowledge (used to be a midwife/OBGYN maybe) that claims childbirth is an orgasmic experience for all mothers and that they're/we're all missing the point if we're not*... He was on Radio4 Woman's Hour a few months back. Needless to say they kinda treated him like the deluded nutter he is he may have missed the point a little and that not all of us find it arousing and for some it's highly traumatising.
In fairness to him, he did state that women are 'trained' to medicalise pregnancy/childbirth and that there is probably more 'intervention' (as in pain meds etc) than is 'necessery' and that nature usually does the job pretty well, but, well. I can't see me having DC1 at home because I trust nature not to screw things up royaly.
Because our vulvas, breasts etc swell during childbirth, as well as throughout pregnancy, it must mean we're sexually aroused...wnker, plus some other freudian toss stuff to do with women being happy because babies represent the penis they never had...blahblah... Also, as we produce large amounts of Oxytocin and endorphins during childbirth (same as during sex/orgasm) that of course means it's the same thing.
I have no doubts some women may feel they orgasm during childbirth, and kudos to them, just please don't tell the rest of us we're "doing it wrong" if we don't...
If anyone's interested in the work behind this, or natural/'Spiritual Births' (which seems to be the driving motive behind this theory) look at May Gaskin's book "Spiritual Births".
I apologise if anyone if offended. If it floats your boat, go for it.
