My friend Bethany, is 14 and has . She tells me I should try it too. Should I?

My friend Bethany, is 14 and has with her boyfriend. She told me the first time was a little painfull but the second time felt great. From what she tells me, is beautifull and fun to have. I am also her age and have a friend who I want to be the "one". Even though I am Christian and beleive in after marriage, I am thoughtfully considering having now. What should I do? I really want this guy to be the one but am afraid of Pregnacy and STD's and stuff.
