Trannies are the ultimate practice gfs. I know what you're thinking, but let me make my case.

>ultra low expectations, all you have to do is not fetishize their dicks and they'll be all over you
>extremely submissive, won't be able to turn down your advances
>due to their imitation of REAL female nature (kind of disgusting to be honest but you're just there to get exp and get out) they're very easy to test different things out- all they do is study how to seem like a girl, so they won't notice how unnatural and varied your approach is
And the best part? Clean up. No need to ghost them, pretend to be boring, reveal your power level (they're so desperate they'd stay even if you went full /pol/)- ALL YOU HAVE TO DO

>make them kill themselves
No mess, no slow fade, no one alive to talk shit about what a jerk you are. And it's SOOOO easy too. I mean, they'd probably end their pathetic lives on their own anyways, since the freaks are so wont to do, but you can accelerate the process.

>point out every masculine thing about them and act like it's their responsibility to fix it
>point out REAL girls that are more attractive than them- even if the girl is ugly to REALLY crush them
>touch their dick if they hate it
>ignore their dick if they like it
>talk about wanting children
>they won't leave a note because they know nobody cares

Afterwards everyone will give you sympathy too, which is a great way to move onto a REAL girl.

It's all those abominations are good for, anyways.
