Virginity is a social construct to keep women under control; if you're a standard 1st year uni student you are only 18/19.
My advice is to learn how to interact with people, learn how to flirt and how to read the signs of attraction (when someone is attracted to you), and just have FUN. Much of the enjoyment of having civvie (in real life/not escort) sex is the thrill and *ping* of the initial attraction, the spark, the lead up, the conversation, the getting to know each other, and the wondering and hoping that sex will actually happen.
If you think you are going to "get away from masturbation by booking an escort" then you are very much mistaken. Let me tell you: you have genitals and a sex drive, the urge to masturbate will continue for many many (many) years yet.
