Sexual changes in the mother
The commonest change is loss of sexual desire. A very large majority of mothers notice it, and it may take up to a year to return to anything like normal. In some women, whilst it comes back to some degree, it does not return to its pre-pregnancy level, and reduces after each child. It may be partly due to the hormone changes that go with childbirth and breast feeding. In some women it is a normal sign of their adjustment from woman to mother.

For some women intercourse is mildly painful, and they have a dull aching sensation which can persist for many months. Provided healing is complete, the pain is not a reason to avoid intercourse and it does not mean that anything is wrong. Things can take a while to settle down.

Another change is slowing down of arousal, possibly because of changes to the layout of the genital area, needing a different type of touch. The vagina may be less tight and give less friction. Fear of pain after stitches may interfere with arousal. Worries about contraception, or fear of another baby too soon will also slow down arousal.

Orgasm may be delayed, partly due to any of the above, and also due to changes in the way the clitoris is positioned. Changes of sexual position or angle may help with this.

Whatever changes you may experience, with discussion and understanding from your partner you will be able to make the transition to motherhood easier. If you get stuck, talking to a therapist is probably a useful next step.
