Had a baby 4 months ago

Hello everyone.

Whenever I'm aroused and my partner is fingering me just resently he has been sticking 4 fingerings in, it felt good just a little and but now I feel mortified that he can now fit 4 fingers into me😮😮

Is this a bad thing? is he still able to feel me and get off whilst he's inside of me? Does he feel like it's a cave when he's inside?

I now feel like that saying, throwing a bar of chocolate into a cave or a hand pocket😓😓
