I don't think age really has anything to do with the "right time" to lose your virginity. It doesn't matter how old I am, I probably won't sleep with anyone unless I'm in realtionship, and seeing that I'm not, the point is mute.
There's no use in hypothesizing the right age. It's like testing out "the effect of the age of virginity lost on the sucess rate of marriages /happiness /success in life" XD I'll lose my virginity when I find the right person to love, and until then I'm in no rush.
Oh, and whatever!, congrats on your pregnacy
