Yes, a man can be raped by a woman.
Where I live it is not considered rape unless the "rapist" penetrates.
In college, I took a class on domestic and sexual violence and the instructor told us she knew a guy who was sexually assaulted by an older female camp counselor. He was 16 and at an away camp, when one night an older female counselor came into his tent while he was sleeping and had sex with him.
And it actually happens a lot more often than people realize.

Yes, It's involuntary sexual advances. That's rape.
