You just sit him down and explain it's something you're not ready for and would like to wait. If he isn't understanding of this, it's a clear sign of what means more to him in your relationship. If this is something you really do want to wait on, never let anyone talk you into it. If the guy really cared, he would respect your feelings about it.
wow hon you are YOUNG.
make sure that if you choose to have sex, use a condom and get on birth control. you can go to planned parenthood for birth control without your parents having to know if you need.
you simply tell him no. if he continues to pressure you i'd suggest distancing yourself from him. he has no right to make you or pressure you to do things you don't want to. if your scared of him that he will force you, talk to an adult ASAP!
You just tell him no. You need to set boundaries for yourself and tell him what you are willing to do and what you aren't willing to do. Make sure he understands that you don't want to risk pregnancy. And if he keeps pressuring you, then you should distance yourself from him. He has no right to make you feel uncomfortable. good luck.
thank you all! i know he will understand. i have told him no about quite a few things in the past. but this just seemed different. i dont want to have sex until married and thats the same with him. i just dont want to get pregnant if we were just messing around! thank you again!
