text: It depends on society.  In western cultures, generally 18 or older, preferably after being married.  In reality in these cultures, many have lost it in their teenage years to boyfriends/girlfriends.  In other cultures, women are married as young as 10 to men and lose their virginity then.  It is tradition and the way things are.  So it really varies depending on who you ask.  I lost mine at the age of 21 to a girlfriend.  When the time is right, you will know and that is when you will lose it.
