Taken from another forum, this was part of a discussion:

I think I know what the OP was talking about when he said he didn't like having a guy wash his hair.
A shampoo can, and should be, much more than just washing hair. When a guy has his head back over the sink, and a pretty woman is running warm water over his head, running her hands through his hair as it gets wet, then applying the shampoo to his hair, that can be a very sensuous experience.
When she massages his head while she lathers his hair, she is rubbing his temples, lightly sliding her fingernails across his scalp, running her hand from his forehead back over the top of his head, with warm running water....that can get a guy hard. If she talks with him while she's doing this, and she has a sexy voice, all the better. A guy can't do this with another guy! It's not the same.
I wash my girlfriends hair when we're in the shower. I stand behind her, and she's a few inches shorter than I am. She leans back against me, and I slowly massage the shampoo into her hair. Her hair is a couple of inches shorter than shoulder length, and I can lather all of her hair at once and I take my time rubbing her head slowly. I can feel the tension leave her. The feel of her hair in my hands,the scent of the shampoo,her body leaning against mine...I could do that all morning.
When she gives me a shampoo in the shower I kneel in front of her, licking her pussy while she spreads the shampoo through my hair. She presses my face against her as she massages my head, holding it there.
A shampoo can be a sexual experience. You can't fuck in a salon, but if the ambience is right, and the shampooer is sexy and sensuous.... there is no similar experience. It is unique to a good shampoo.
Do the women reading this enjoy a shampoo by a man as much as by a woman at the salon? If you find the guy real hot and sexy....doesn't it make the experience that much better? Isn't the shampoo over with far too soon?
