If you re write that using full words. I could probably give you a little advice. I couldn't understand what you were trying to understand.

It is probably just your body adjusting to having sex. I still get pains after sex once in awhile for no reason at all. But if it is constant pains everytime you have sex it might mean that there is something wrong so if you are really worried I would get into a doctors office to get checked to make sure everything is alright

Use a condom!!!!

Is 20 minutes of fun worth 18years of taking care of a child? Keep one in your pocket, next to your/his bed! You can get them at doctor's offices, maybe the school nurse has some even. Your pediactric doc should have some. Or, you could buy them, of course!! It would be nice if he bought them, cuz it is sort of ambarrasing to buy... But, it's your body, your life, you should take charge. Even if your not planning on having sex, just keep them nearby and handy! Sex still feels good with them, and it'll feel real good when a two year old isn't in the next room running around screaming.

So if your're mature enough to have sex, be mature enough to use a condom!!!!
