'Several studies argue that male-male prisoner rape, as well as female-female prisoner rape, might be the most common and least-reported forms of rape, with some studies suggesting such rapes are substantially more common in both per-capita and raw-number totals than male-female rapes in the general population.
Research from the UK suggests that almost 3% of men reported a non-consensual sexual experience as adults and over 5% of men reported sexual abuse as a child. This does not take into account the possibility of underreporting. Recognition of male on male rape in law has historically been limited; the first successful prosecution for attempted male on male rape in the UK was not until 1995.

Much like female erectile response and contrary to popular opinion, male erectile response is involuntary, meaning that a man need not consent for his penis to become erect and be placed in a woman's vagina. Penetration of a man by a woman is possible through forcible stimulation of external male genitalia or the anus, or by forced penetration of the anus with the use of strap-ons, dildos, other foreign objects which could include a tongue (inserted or external) in forced oral, forced digit manipulation, and digital penetration. A woman could also force a man to perform oral sex on her. Rape of a man by a woman could also occur when limited sexual activities are agreed upon and a man's penis is placed in a woman in violation of the limits that had been set. Rape of a man by a woman is thus possible in several ways.
However, male victims of sexual abuse by females often face social, political, and legal double standards. While gender-neutral laws have combated the older perception that rape never occurs to men, and other laws have eliminated the term altogether, the double standards still remain.'
