5mo pp and having issues...mommy & daddy time..

Dustilou

Hello Ladies.. I am hoping I might find an answer here. I had my twins and my first c-section in January and I healed fairly well..but I am having issues with mommy/daddy fun time. Every now and then it feels like my incision site is getting "hit" from the inside, and last night he pushed a little harder and it felt like it ripped. I know it didn't, but is this normal??  Also ever sense the delivery I haven't been able to complete the mission..so to speak is this normal too...OMG!  

On a different note is it normal to have patches of numbness also?? 

TIA..a completely embarrassed Dustilou..
