Work Inside A Vigina I Can't Feel Much Inside My Vigina Is It Normal?

I can't feel much inside my vigina is it normal? - work inside a vigina

I'm in the middle of the 20s, never had sex. I have tried to put a stamp on my V, but is very sensitive and painful at the entrance. I tried to put my finger in, I moved, but I feel no joy, just depressed. Can anyone tell me whether this is normal? Am I not enjoy sex at all ......:(
