Rape: Sexual intercourse with a woman by a man without her consent and chiefly by force or deception
Marital status is irrelevant.
My ex-husband used to "dream" that he was having sex and then lo and behold he'd start doing things to me in his "sleep." He'd wake me up out of a sound sleep and then when he "woke up" he'd tell me he thought it was all a dream. BS
He also didn't want me on antidepressants because it took away my sex drive. Truth be told, I just didn't want to have sex with him. Medication was beside the point, but he couldn't have his tender male ego bruised over the thought that not every woman wanted him.
