I had a c-Section almost 3 years ago. I wish I had better news for you, but I still have tenderness at times during intercourse. As well as before bowel movements. And anytime I get pressure in that area. I also have ovarian cysts (so that could be compounding the pain for me). But... it has gotten A LOT BETTER and LESS FREQUENT as when I first had the c-section. And let me say this too. I also had a tubal ligation at the same time (wich also could be making my experience worse).
But, if I could have more kids (wich I can't) I'd have them C-section again. In my experience, even with the continued issues, I've had much LESS pain from the c-section, then from the pain I've had due to complications from Vaginal Birth (still having issues with that too).
But... the part that bothers me the most is having to be more careful during intercourse. It's very important to tell your husband if he's hurting you and ask him to shift, change positions, amount of thrust, whatever is needed to make it more comfortable for you. If he learns early on to be easier with you (the pain is also more frequent during ovulation and right before mentration for me, so my husband has learned WHEN we have to be more careful) it will be easier for both of you. IT CAN BE VERY FRUSTRATING and EMOTIONAL due to the desire to be back to where you were before. But it WILL GET BETTER.
It's just important to comunicate with your husband and not give up on intercourse or eachother. If you both go into it with a loving mindset you'll find soon it won't bother you as much if at all.
Like I said, it's been almost 3 years and I have SEVERAL other Issues, so you may have better luck. But my pain is cyclical depending on the time of the month and blood flow to my uterus.
Ok, this may be getting a little personal... so forgive me if this seems a little blunt, but I find it less painful if I'm on top during my tender days.
Hope that helps.
