Guys!!!

So every time i feel my vagina, its like... theres this obstructing thing that feels like a lil penis right inside my vagina.

After doing some research, i found out it was my cervix... but damn!! Shes right in there!! And i mean, like my first knuckle doesnt make it inside my vagina without feeling my cervix. Is this normal???

Also, my vagina seems incredibly short... like shortly past my first knuckle of my index finger is the back wall... i need some help with the normality of this!! Like when i put in a tampon, she goes PAST my cervix but hits the back wall of my vagina right away (honestly it gets a lil painful)...

Whats going on??
