So I'm link-hopping from this wank and I find this.
Apparently these things are full of truthiness:
1) All gay men have anal sex
2) No cis woman (or straight man) ever has anal sex
3) Doing "extensive research and reading" makes you a sexpert. You don't have to be a gay man to know everything about gay male sex apparently! (Helpfully, all gay men have sex the same way apparently too!) She and Dan Savage should get together: he knows everything about cis straight women and sex, she knows everything about cis gay men and sex, it would be a match made in wank heaven.
4) If you have been penetrated anally, keep a timer around. If you are sore for one minute past six hours, go to the doctor RIGHT AWAY because you have a tear. But if you're in extreme pain for less than six hours, no worries I guess. (I was once a teeny bit sore for a whole day, and was uninjured, but that's okay because as a cis straight woman I couldn't have actually been having anal sex anyway.)
Also, from her writing, I have learned that putting a dick into an ass without any plugs or other stretching first is simple and easy and never causes problems, even for two people who are completely inexperienced. Lube is just that magical! I have also learned that spreading lube around the outside of the anus will work fine, it's not necessary to actually get it in there.
Also also and unrelated to anal sex, I have learned that "I love you so much that I have to show you or I’ll explode" means the person wants to set up some kind of flower petals n' scented candles experience, rather than being a prequel to people fucking each other senseless against the nearest available surface.
The amount of joy I have found from things she's written, both posts and that one fic, is immeasurable. She's so earnest and so certain and so clinical in her porn.
