Lost feeling

Okay, so I am almost 7w pp and I have been cleared to have sex again. Ive never been able to finish with just penetration, so we use a vibrator on my clit to help things along.

It seems now, I have lost the feeling a lot of feeling in my clit so I don't finish as easy. Has this happened to anyone Else? And has it came back after time? I didn't want to ask my doctor bc my mom was in the room and even though she has seen my vag now, it is still weird. I don't get it and I miss the sensation. Someone help.
