I think we need to approach teens and sex with the same message we approach them with about drugs and smoking. we are strong with our teachings that these are UNHEALTHYand often DANGEROUS behaviors. teens having sex is also dangerous, especially younger teens and adolescents.
We don't tell kids, "you shouldn't smoke, but if you decide to go ahead, here are some light cigarettes." We send the message, "Don't Smoke!" Kids need to know that sexual activity may lead to STDs and AIDs, AND that Condoms DO NOT fully protect them. Also, STDs or not, pregnancy or not, there are serious EMOTIONAL and PSYCHOLOGICAL consequences that go along with early sexual activity. WHY are we telling our kids that it's ok if they make that decision, just use a condom??? That's like telling them it's ok to use drugs, just be careful about it. that would be irresponsible, not to mention insane!
IF a girl were to be assaulted, it is doubtful that the perpetrator would use a condom. It's usually not about the sex, but about control. Also, since you mentioned that argument, IF she were to take him to court, he could use that against her, calling it consent...but that's a whole other issue.
No, I think our girls need to be protected by family members, fathers, education and self esteem. Don't give your daughters a water pistol, then send them into a hungry lion's den.
