Pussy when I’m being casual, cunt if I’m actively talking dirty to a partner.In my head, sometimes “piglet” because I read that the Latin word for piglet was used as a childish euphemism for the vulva, similar in tone to “hoohah” and I thought that was very cute.
Jayjay when I was a kid. In my siblings girls had jayjays and boys had doodles. Kitty or pussy now unless I’m at the doctor.
