QUESTIONS,please answer if you can...?

All I can go on are the people I know and I dont know anyone that is married that was a virgin on their wedding night,I would say the average age of loosing virginity from my friend and my high school was 16-17 and we all used condoms most of the time unless your with a girl that you trust and shes on the pill the times without a condom most people pull out to slim the chances of pregnancy,not saying this is all right just the way it is
