Please do not laugh.......?

I had my baby 8 months ago, he was 9 lbs and a forcepts delivery. Not to be absolutely disgusting, but to fully understand this i need to explain (sorry haha). The doc said he was just going to tug on the baby a little bit and then I could push him the rest of the way out, my baby was face up and he wasn't budging after hours of pushing. Next thing I know, the forceps are in and the baby comes out all in one shot. He did not cut me ahead of time or anything so I had 4th degree tears which is the worst tearing possible, I tore all the way to my rectum and walked like I got shot in the crotch for over 2 months post par. My question is, I don't regularly do kegals like I should, but I do them here and there, and the outside of "down there" is fine now, but when I do exercises on my back, air goes in there and it's kind of uncomfortable. Does anyone else have this problem or know about it or advice, something I'm just concerned. ?
