I am not sure what is intimate partner violence but 40% of victims 'being hit' by their partner are men, and in most cases of 'being hit', women start it - predominantly under the assumption that no one will hit them back because a) they are women b) society still goes gaga after 'women and children' and not men c) in practice women are protected from any consequence of hitting a man but men are by default assumed guilty until proven innocent.

For example, while VAWA talks about non-gendered domestic violence, in practice only one partner is arrested so the other can be allowed to take care of children and in 100% of cases where both parties got into a physical altercation it is MEN who end up in jail and with a restraining order.
