The DoD estimated that 0.4% of heterosexual or other non-LGB men had been sexually assaulted over the previous year, but an estimated 3.7% of gay or bisexual men - nine times the rate of LGB men - had been sexually assaulted. The difference between sexual assault rates for gay or bisexual men, as opposed to heterosexual men, was even more stark, Rand said. That's about twice the 4.8% of women who reported being heterosexual or otherwise non-LGB estimated to have experienced one or more sexual assaults during that time frame. Defense researchers in 2018 found that an estimated 9% of lesbian or bisexual women in the military had been sexually assaulted at least once in the prior year, according to the study.
