Advice!

Hey guys! So I'm a virgin and I started dating this guy about a month ago. He's my first real boyfriend and we're a very good match with each other, but the sex talk came up. He's adamant about sex before marriage but he doesn't care if we wait years before we try that (18 and 20 years old so we aren't in a rush to get married) but I'm not sure if/ how I should lose my v card?
