Well although I lost my virginity when I was 13, I regretted it. I did it twice with her before breaking up with her 7 months later. After realizing my mistake I waited nearly 3 years before I was with someone else, which of whom I am still with, engaged, and have a daughter with. Maturity is always more important than age, and I would say that I know more people who graduated with me who are still virgins than are no longer virgins. You're in the majority! Be proud, any guy worth having will wait, no reason to rush, you have the rest of your life.
it doesnt matter if youre 15 and a virgin. you shouldnt worry or feel that you should have lost your virginerty most people dont until theyre 18+ and its better to do it later in life and making love for the first time is better if you the person you first did it with is the only person you ever want to so find the right person before you do anything like that
