You can stay as male looking with some little steps..
Explore till you unlock the University District, you will find an old mansion..
Once you manage to enter in it (bright day as you need to find the key) go in the little room, there's a pedestal and a table..
You can either use the pedestal as many times you wanna (restoring sleep together with others stats, so no changing dreams as no need to sleep), you can use the potions to change yourself (check Wiki for those, will be anyway temporary and will wear off if you drink from the pedestal) or the Apparatus..
Coffee also having the same effect..
In the sitting room there's another old book..
3 spells in it : Magic Resistance, Glamour, and Z-cup (save before read it if you wanna avoid!)
Magic Resistance together with Physical protection spell from the shaman (Downtown in the park) can protect you from night changes.. there's also the Dreamcatcher in the shop in Dwarf District..
You can still use the cheat in the phone to set your MC as you like more..
At the end is a transformation game.. so.. shit will happens as you explore more..
