Lactation during intercourse


Lactation during intercourse


your avatar   Rog, 47-year-old man

I have been in a very romantic love relationship for 2 years. During the past year when we are making love, she starts producing milk in the middle of intercourse when I am caressing her nipples. We both see this as a very heightened sexual activity but are at a loss as to why it is happening.

Pregnant women will at times lactate during high sexual arousal. Arousal will trigger the release a pituitary hormone called oxytocin, which in pregnant women stimulates the uterus to contract and will act on the mammary glands to trigger the release of milk. Non-pregnant women are known to lactate during arousal, although it is not typical. There is probably a hormonal reason why this happens with this partner and she might want to discuss it with her gynecologist just to rule out the possibility of a problem.
