PP sex while breastfeeding (feeling loss)

(TMI, don't continue reading if sensitive to sexual information)

I had a baby about 5 months ago. Sex no longer hurts, but it does not feel nearly as good as it use to. I almost feel a little bit numb down there and only a few positions give me actual sexual pleasure.

This is pretty embarrassing so I am posting anonymously on it...

When i felt with my finger, my vaginal walls seem thinner, and not as "spongy" to be honest everything feels different down there...

I am still currently breastfeeding and even if I use lube sex just isn't "mind blowing" the way it use to be.

Not sure if breastfeeding plays a roll in this at all??

Does anyone have any experience with this? Any information on what exactly is going on or if it will get better?

(I have posted this in several groups hoping somebody would give me answers, or have any advice .. so sorry if I am spamming it in a few groups.)

Thanks!
