Ty decided to accept Frankie's implied offer and meet her after school. However there sex in this world affected your appearance.
If you penetrated your partner, you would appear a bit more manly, and if you got penetrated, you would appear more feminine.
There was a chance you could even lose one set of genitals if you had sex the same way too many times in a row.
It would take so many times to lock yourself into one gender that you would have to do it on purpose, but whichever type of sex you did more often generally established you as a dom or a sub.
"Do I really want Frankie to penetrate me? Shouldn't I want to be the one penetrating her? I used to be a guy before all this, after all...", Ty thought to herself. She tried imagining herself penetrating Frankie instead of the other way around, but it wasn't working, she was still aroused as a girl. What should she do?
