20 yr old virgin

Guys im 20 years old and im legit such a fricken prude. Ive had multiple chances to suck dick and have sex and everything else, its just i get so nervous and insecure. I always feel like my vag smells or is gonna taste weird or im gonna bite his dick off or something. This is seriously the ultimate struggle i just wish i could do these things so badly im so frustrated and upset. I feel like ill never experience any of this stuff. ):
