Suggest Remedy For Numbness In Vagina

I'm a 46 yr old woman whom is very aware of my body. I had a situation recently during oral sex with a new partner and now I am freaking out. He was lightly sucking my clitoris between his lips and then he bit my clitoris so hard that I thought I was going to pass out. Now the tip of my glan is no longer exposed and it has always been exposed in the past and now my sensitivity is gone. Could he of actually bit the tip of my clitoris off and if so can I do anything to get the sensitivity back or am I ruined forever.
