Really Experienced
This likely has a lot of truth to it. I once posted a story on Literotica under an account where I claimed to be female; it was a girl-on-girl story, and I was curious to see whether people would call it out as having obviously been written by a male author, or if they'd believe and accept that it was from a female author. It turned out that no one expressed any opinion on that, but I DID get a fairly large number of messages from guys wanting to hook up online, do sex chat, trade nude photos, etc. The fact that this was a first-person story from a "female" author who clearly identified as lesbian didn't deter them in the slightest (and no, I didn't get any propositions from women or even anyone claiming to be female). On the other hand, when I wrote similar stories under a male-identifying account, the only comments I got were about the story itself.There are no girls on the internet.
If you're female and you don't want to get messages by horny guys, you might choose "male"
On the other hand, if you're male and want to get additional attention, you might choose "female"
I'm not saying that a bunch of the "male" accounts at CHYOA are actually women who are trying to avoid being propositioned, but I wouldn't be surprised if that were so.
