Firstly, the changes which are most obvious are to the body shape. Post natal exercises will help improve muscle tone and repair the stretching to the pelvic floor. A return to the normal exercise regime when possible should restore the outline to something approaching the pre-pregnancy shape, but few women retain their waist measurement precisely, so expect to increase by a few centimetres with each baby.

Less obvious changes are those which happen in the genital area, both within the vagina, and the other sexual parts. The clitoris may be in a different place relative to the vagina. This can mean you have to adjust your position to get an orgasm.

Some women find intercourse causes a dull aching sensation for a few months, and even as long as a year. Provided healing has occured there is no reason to stop making love if you want to. Imagine all the changes to the muscle structure, and it is clear that recovery from that may take time.

Inside the vagina there may be little crevices and crannies which are new. They are normal, and you may find after a bath that a little water is retained so drying is important. Also, the vagina may feel less tight than before, so the amount of friction for each partner may be less. This could mean the time taken to have an orgasm may be longer.

Another hot issue is "Whose breasts are they?". For some couples breast feeding can affect how they feel about breasts as sexual organs, and this can change their sexual activities too.

Finally, the sheer physical exhaustion caused by the whole process can make the very idea of lovemaking seem like an impossible mountain to climb. Fortunately, all these effects get better in time!
