As an LD breastfeeding mom... I gotta say that having milk shoot out your breasts while Oing does not give one the 'sexyness' feeling. And for one who is already LD... it isn't so easy to 'pump' before sex, especially if the milk has not let down... and I don't know that it puts one in 'the mood' either.
There is not one shred of helpful advice here... just a lot of empathy for both parties. (Chrome and Mrs. C.)
