Please can I have all your stories of positive outcomes (including tearing but good recovery!) after not bothering to do this? DP has just spent 10 mins ineffectually thumbing at me and I don't think he's keen to repeat the experience; I can't really reach to do it properly, but the midwife running my birthing class was APPALLED that I've got to 37 weeks without doing it.
Is it actually effective or is it a luck of the draw combined with genetics, position, size of baby, not going hell for leather while crowning...?
