I avoid the female references in speaking of myself and I don't think I've slipped up yet. I however do feel really awkward when my family (those who I've "come out" too) use the "she", "her", "daughter", "granddaughter" etc. and my birth name too even pre-everything, but I let it slide because I know it's difficult for them. I avoid using my birth name wherever I can as well. Can't escape either during job interviews though... much to my discomfort and annoyance.
But, I have two furkids (feline) and my mom always refers to me to them as "your mamma"... I let that slide too. But wish she'd use "daddy" or something, 'cause that's how it is. But, I'm sure that will start happening with the male pronouns after I'm on T and clearly, visibly male.
