CMV: I don’t see anything wrong with letting a child see sex scenes on TV.

Honestly speaking I am a sexually awkward person. Anytime sex is mentioned I feel weird. I hate this and I blame my parents. They hid sex from me and left the US educational system to explain it to me. Why can’t I be able to watch a movie or show that may show brief nudity with a 4-13 year old? If this was the general attitude there would be no sexual immaturity. The child would grow up knowing sex is normal. They would know sex is or can be an intimate relationship between people and everybody will experience it. Such a common thing shouldn’t be so taboo. We shouldn’t be afraid of our bodies no matter how fucking old we are.

Most movies and shows don't portray sex realistically.

Some examples include, but are not limited to:

- women always keep their bras on
- oral sex is rarely presented, and if it is, the female partner usually doesn't receive it
- sex is over much too quickly
- the sex is "cinematic" and not representative of real, happy, communicative intimacy
- the sex veers towards sexual assault
- the sex is actually sexual assault
- LGBT sex is rarely portrayed
- safe sex isn't portrayed

A child who sees this might not grow up sexually immature per se, but they'll have some pretty funny and wrong ideas about how sex works, at best. At worst, they won't really get consent, safe-sex, or the existence of non-hetero relationships. 

Now, you're probably thinking, "Ah hah, that's where the parents come in!" And sure. Parents can sit down and explain all this to their kids. But many parents are really bad at The Talk, particularly The Talk modified for different ages. If you can't contextualize sex for a child, then showing it to them can do more harm than good. Likewise, if you misinterpret your child's level of maturity, no amount of context can make them unsee what they saw.
