So lets talk about sex.
yes, sex. Sex in fanfiction, to be specific. Affectionately called a "lemon", fanfiction sex is something like sex in a older romance novel. The stories are meant to be loving and interesting. Sometimes it's just meant to make you cream yourself. Still the sex is ridiculously unrealistic.
Ten reasons why:
1. what was the last yaoi you read that involved a condom?
2. Why does anal sex ALWAYS hurt? it doesn't in real life?
3. All first time sex experiences are beautiful and hott; not awkward like real life.
4. When was the last time you read a fanfiction where the girl didn't bleed the first time she has sex even though in today's world it very rare?
5. Why is there no sexual diseases?
6. How come only men seem to get pregnant?
7. When was the last time you read a fanfiction where giving head hurt the throat?
8. What was the last non-con that you read that was actually just sex-play and consensual with a safe-word and everything?
9. Why is everyone's dick HUGE?
10. Why do people finsih/cum together?
[keep in mind GOOD fanfictions are not this way... and some good fanfictions are this way, but are still not realistic.]

Tell me the name of any fanfiction or authors that write their sex realistically. I'm honestly loking for them.
