What the hell are you doing having sex at 13???? I'm almost 15 and that is the furthest thing from my mind, thank you very much!
To anwser the first question, I do not think that the information should be withheld from anyone at any age, but I do hold to the belief that people should at least wait until they are somewhat mature to start having sex, ya know 17/18. Call me old fashoned, but i'm personally gonna wait till i'm married.

if you can't at least commit to sharing your life with this person, you shouldn't be at risk of having to commit to bringing another life into this world. A child's life is worth more than that. Don't get me wrong, I love kids, espically when they're little.

they're so cute! But I also respect them, believe it or not. Anyways, i'm babbling.
Good luck to all of you!
