What does it mean when your boyfriend wants you to be his first to lose his virginity to?

it means he wants to have sex with you before any one else. ---- That means that your boyfriend is a virgin and he wants to have sex for the first time with you. Remember, you are a part of this equation. If you are not ready to have sex or you do not want to have sex, you do not have to. Pre-marital sex is not a requirement in a relationship.
