People just keep talking to me too when i switch - tho i think that's just cuz they don't notice. it might be helpful to find out (if poss) what age the protector is (all our protectors are actually kids in age, but don't feel like kids). but they also don't like to give out names or ages. so it might be difficult. one of our kids got mad at the t when (and the t knew) she used words not approproate for a kid -but the lil also couldn't say she was uncomfortable to an adult.
i agree with free on the sex thing - as a betrayal. but you don't need to feel embarrassed i don't think - you're seeking info and that's great. that's how we all learn.
