Oh man this thread is scaring me!! I have a 16 year old son and a 14 year old daughter. I personally just feel 14, or even 16 is too young for sex and all the consequences that goes along with it.
I just hope when the time comes I wll be as understanding and open as you are.
Hopefully with you working together with your ex your son will see the importance of really listening to what your saying and know you both are just looking out for his well being.
I hope it all works out for you and I'm sure you know, your not alone when it comes to raising teenagers It's not for the weak, that's for sure!!
