Both sides of the "virgin" debate are completely nuts, most of the time... There is no NEED to lose your virginity as soon as possible, it wont make you a better person, "unfortunately" it's a kind of status symbol for boys in school to have had sex. For girls it frequently causes the "slut" label to appear, regardless of how many times you've had sex, it's the nature of teenage girls to be jealous and rude I guess...
On the other side, why protect it like it's the holy grail? You'll never have sex like teenage sex, parents should remember this and allow their children to lose their virginity whenever they feel like it. In many ways the first kiss is a much more memorable and important event in most young peoples lives. Also, why is it called "losing" your virginity, it sounds so negative, cant we cook up some happy word for it instead, or at least a somewhat neutral one?
Sell whatever you want to sell, as long as all involved parties agree I don't really care, nor should all the arm-flailers around the world. Promise rings... Meh, nothing wrong with them I guess, it's a way of committing to a belief and I'm all for people being allowed to have their own beliefs. Personally, I couldn't be bothered, similar to how most of my life choices go... Whatever works, you know...
Wait until whenever feels right/your so doped up on various substances your unable to make a sentient decision and it'll happen for you... (yes, that goes for both cases Oo)
