Lesbian relationships
The CDC has stated that 43.8% of lesbian women reported experiencing physical violence, stalking, or rape by their partners. The study notes that, out of those 43.8%, two thirds (67.4%) reported exclusively female perpetrators.
On Facebook, Ken Francis noted:
The National Violence Against Women survey found that 35.4% of lesbians experienced intimate-partner physical violence in their lifetimes, compared with 7.1% for women for heterosexual women. The CDC’s 2013 National Intimate Partner and Sexual Violence Survey reports that the lifetime prevalence of rape, physical violence, or stalking by an intimate partner was 43.8% for lesbians, and 35% for heterosexual women, while it was 26% for gay men, and 29% for heterosexual men.
