I'm guessing your doctor told you to wait six weeks after childbirth before having sex -- typically the standard practitioner recommendation. You'll have had your postpartum check-up and your doc can make sure everything's healing well, especially if you had an episiotomy.

If you've given birth before, did you wait the full six weeks before getting it on? And if you didn't, um, how'd things go?
