Personally, I'm a fan of waiting until you are married to have sex (I'm sure some will suggest I am a prude). That said, I would ask, "Why would you have sex now? " In my opinion, apart from my personal religious convictions on the matter, now is not a good time.
You are still in high school and you have a lot to focus on besides sex. Further, you never know what is going to happen in your relationship. Congratulations on being together for five years - that is a pretty huge achievement.
Also on not just rushing into the physical end of things! Waiting that long to kiss is pretty cool too.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
