ok well first off. I truely believe a person should live on their own for at least a year before getting married. So get out of your parents house! lol. Secondly i am kinda old fashioned as well, and i can understand why your parents feel that way. Now if your like me, i'm a virgin, and proud of it, i know i would never let anything happen, because i have made a vow to God and to my parents not to. Unfortunately for some reason a persons word isn't good enough. Theres really not much to suggest that makes it a win-win situation. Your parents just have to trust that they have raised you well and that they can't shield you from making your own decisions however tough they may be. Telling you not to go and do whatever you guys may or may not have planned to do won't stop you if you did plan it. They just think you'll have sex, try to reasure them that you won't and explain that whether your in Las Vegas or at your boyfriends house stuff can still happen, they just need to trust that you know better.
