Yes, by both men and women. One gay man that was cutting my hair rubbed his erect penis on my back in the middle of the hair cut. I was not happy. I gave him a dirty look in the mirror and he stopped. He finished cutting my hair and I paid him, never to return to that salon.
But I've been fondled and pinched by men and women. I don't mind the women, as I am straight, but I don't appreciate the men doing it. But I don't fear for my safety.
