Most physicians reccommend 6 weeks until having intercourse, regardless of the method of birth. Few women that I have spoken with personally actually heed that advice, and most proceed with relations once all of the bleeding has stopped. The problem with sex and cesareans sometimes comes from the fact that your abdominal muscles have been cut through, as well as your uterus. Your abs are often used during intercouse, depending on positioning, and your uterus contracts during orgasm, so it is important to be sure that full healing has ocurred before doing this. This ias also why you are not alowed to lift anything heavier than your baby for the first 6 weeks as well. I never heard that you had to wait 2 years before becoming pregnant agian, but you would want to ask a physician about that. TTummies take a lot of time to get back to their normal shape and size after birth. Breast feeding helps to reduce the size of the uterus and also with losing weight. Exercises which are helpful in this include abdominal crunches, yoga, pilates, or any core strengthening program. be sure to get your doctor's OK prior to starting an exercise program after cesarean, to ensure that your incision is healing well.
