Is it normal to be an adult virgin?

It seems since it was Ok to come out as a Homosexual it seems that there a another type of people coming out confidently as well those who haven't experienced sex,Virgins. In our society there seems to be such a pressure to get sexually involved with others than yourself between the ages of 12 and 21. However due to shyness, religious up bringing, and "inadequacies" Before I lost mine at 27, people used to ask me about my masturbation habits or even expose me as a virgin. So how OLD are you allowed to be a virgin till if you want to get a resonable sex life in your life time?

If you are a virgin would you come out and say you are?
Do You?
Or when you were did you?
