Sex

Dear Daughter,
I know this is a touchy subject but it has to be brought up by someone, so here goes. 
Sex is not a toy and it is not a weapon.  It should only be experienced when you are emotionally ready and old enough to understand what consequences could bring.  I know at some point you will want to do it just because it will defy your Dad and I but that is not a logical reason.  The decision must be made when love, trust and monogomy is involved.  There is no taking it back something you have done no matter how bad you feel about it.  So make sure it is the right decision for you and no one else.  You are the only one who can say that you are "ready."
Do not let a guy pressure you into it either, if he tries to pressure you then it is not love and he does not deserve you.  He is only doing it so that he can get sex.  Real love asks for nothing in return.  I am not saying that love doesn't take work but sex is not the answer to a problem in a relationship.
Do not sleep with more than one person,  that brings on a whole other set of problems and risks.  Sexually transmitted disease has a higher probability when you have more than one partner.  That is not a gift that can be returned so please be aware and careful of this.  If it makes you feel safer then ask for an STD test.  If they get pissed off because of this request then you really don't want to touch that. 
I am not trying to force my beliefs on you but I don't want the rest of your life affected by a decision you made too early and too young!  It is a very important step in your life and it must be made for the right reasons.  Not because you may lose someone if you don't or not because everyone else is doing it.
Just be sure you really know someone and you feel that they are the right one to share it with.
Just my advice.
