I was told the typical 6 wk thing, after a csection. My mother and father were telling me at 4 wks that I needed to give my BF sex. WTH? I had a CSECTION! I was just having yellow lochia at that point. We went ahead, when we went to our MILs house, because I didn't feel right doing that with my BF in my parent's house since they usually say to wait until marriage, and we should have been married by then. And, I made him use a condom because my fear of INFECTION. I think it was totally stupid. No one should be pressuring a section momma to do anything that makes her feel worse than she already does! And, to boot, my BF wasn't the one putting the heat on me.
With #2, I had stitches in the other place. I am sure we waited the 6 wks.
With #5, I had a slight PPH that I was able to care for at home. But, then I bled for 9 wks. So, he had to do without for that time. I just figured that if there is enough space for things to be open for bleeding/lochia, then it isn't worth the risk. There are other ways to be intimate.
But, my friend has a higher libido than I do, and she said it wasn't but a week after her csections, and she had 3. So, I would go with how you feel. Kymberli
