URGENT!! HELP!

So my boyfriend and I were messing around Sunday (Oct 1st, I believe) and I was giving him head and just playing around and stuff.
Well, earlier in the day, his brother in law had mentioned Orajel for coming quickly and said itd slow it down.
Anyway, we joked around a bit and so on.
Well,
Its Oct 4th and he still has no feeling in his penis..
I cant find anything online and i'm super worried.
Help, someone, please.
