That is a real shame that you’ve gone all this life and not had that experience! I am always sensitive when using my finger. As is said in the post, start slowly, very gently, feathering the clitoris until your vagina starts to dampen and lubricate your labia. Once the lubrication is good and ready, reach for the upper part inside, search for the ‘g’ spot and then go for it, inserting more fingers, the wetter it gets. Then you will come lovely. I did that to a partner as we were kissing goodbye in the carpark at the airport. She virtually raped me orally afterwards. Then texted me from the plane to tell me how wet her panties were and how horny for our next meeting. I kept my fingers for licking on the drive back home. I’m sure that’s where Col. Sanders ad agency got their slogan from!
