Why are people not using their brains?

I have been reading and responding to some of the questions on here and I find some of them so dimwitted that I can't tell the sincerety of it. It is very elementary...Teenagers: If you have sex, you can get pregnant, get an STD or worse. What part do you not understand? Use a condom if you must experiment. Guys...you don't want to lose sensation?? Would it feel better to have sex with a condom or have no sex at all? How can you not know any of this? It is shoved in your face everyday. I love sex, but I am responsible for my actions. Someone please explain to me what is so hard to understand?

I agree in a sense........my annoyance is immature girls thinking they can have unprotected sex without getting pregnant and I post and re-post and re-post over and over.GIRLS- doesnt matter what time of your cycle it is, if you just finished your period, you are on your period, doesnt matter you can STILL get pregnant if you have unprotected sex and yes for the hundreth time PRE-C*M CAN GET YOU PREGNANT! if you dont want to end up pregnant for gods sake just have safe sex or dont have sex at all! AMEN!

I agree 100%!!! If you dont know whats all involved when you have sex, then YOU SHOULDNT BE HAVING IT!!! Its also too late to be asking questions about STDS, and pregnancy after youve already have sex!
