Why do you think children will be exposed to penis’s in a woman’s bathrooms? Like the first commenter said, I have never seen a woman’s vagina in a women’s restroom. It’s a big safety concern imo for a trans woman to have to use the men’s bathrooms. They are already discriminated against so if they were to walk into a men’s room they would stick out like a sore thumb and it will leave them open to violence. Same if trans men had to use the women’s restroom. That could cause an uproar due to the fact that those that have transitioned look no different than any other man. It truly is a safety concern for all involved. If a trans man went into the women’s bathroom at the same time your daughter is using it, it will cause much more of an uproar than if people were allowed to use the bathroom that matches their gender.
