I've found some acceptable workarounds to upping the maximum fem scores for male characters, most only have minor effects. I'll label them with pluses to display their boosts to your max. 1(+) = +/- 5 max points. These results came from some pretty haphazard testing and something may have altered my results so they might not be entirely accurate. If
Have breasts, not talking about large ones, small as you can go, like A-cups. ++++
^//doesn't keep you a categorical male, turns you into a trans, change pronouns to masculine ones and you'll barely notice a difference.
Have feminine hips, basically sizes 4 and up. +
Have a feminine ass, also sizes 4 and up, doesn't work if thickness too high. +
Have large lips. +
Have long hair. +
Balls being size 1 or being a uniball. +
No balls. +
Dicks smaller than 5 inches. +
No beard. +
This basically turns your surprisingly feminine dude into a trap but I guess it's okay for me, not sure for you.
