In UK law a woman cannot rape a man, but that can be done for sexual assault and various counts of child abuse.
There's actually a charity for men who have been raped (mostly by other men) but I believe they have a lot who are victims of women and need support for the trauma as they can't convict.
The numbers of women committing rape is tiny compared to men, it's like .5% of reported rapes or something. I'll try to find the numbers.

Edit: all this stuff in the UK was highlighted when a female pedophile ring was uncovered, they were all groomed by a bloke to do it so I'm not sure if any laws were actually revised, but it shocked the country that women could do such a thing, apparently they are automatically immune to certain laws.
In the cases of child custody, the UK favours the mother over the father at all times, it is only when the mother is psychotic or on drugs that the father may have sole custody, in fact our law tends to give children who are victims of abuse right back to their abusers which is why I don't support some charities who support this practise, NSCPP believe in returning abused children to their parents.
