Actually, he testified they didn’t have sex. She testified she was penetrated and she believes it was with his penis, because she could see both her hands.
As to whether is was consensual, who knows? Was it even actual sex? I don’t know.
I still thinking prosecuting was heavy handed. Was he a cad? Certainly? A rapist??? ...
Sounds imho like the judge was going for a PC-correct sentence, not a just one.
