Well good for you if your using birth control, your very wise about that, and thinking about your future, and you are good role model for these teenage girls, and respecting yourself, thats great"""". Jst remember if your having sex, there is no such thing as safe sex in my opinion, but it want hurt to double your protection, a back up you could say, with his part. Of course im 33 years old and I have children and im married as well, but I remember all the boyfriends I had they wanted to have sex with me, but I always told them no, some stayed with me for a couple months, and all we did was kiss and stuff but, I was young so I didnt know what love was anyway, just all crushes with me, but I was virgin untill I got married. That I gave virginity to my loving husband on my honeymoon,and that was very special. I was about 19 when I lost it. Good luck to you, take a test to see if your pregnant, but I doubt it if you are if you are using total protection. We are here to support you. From mary.
