As a heterosexual woman the excitement for someone being visibly aroused by you is relatable and you will find plenty women sharing the same sentiment if you know where to look. Unfortunately if a woman had written this here she'd be slut shamed by the men and called a handmaid by the women.
This is sensible. It's important to note the context in which both take place; women, you see, are incapable of generating the level of intense connection that two men can create. With men, it's two minds engaged in a spirited dance; both a battle, and a serene escape from reality. Like a firestarter, two stiff rods can be rubbed together to create a roaring fire, in which a deeper understanding of life, philosophy, and nature can be forged. A male on male relationship encompasses that which makes humanity great; the exploration of the unknown, testing the boundaries of power and speed,
A women simply cannot view a man in the same way; thus, she is denigrated. A woman looking at a man is sort of like a dog looking at a television; the dog can see the TV, it can react to it, it may be intrigued by it, yet, the dog cannot have a full conceptualization of what is happening on the screen. It does not understand that it views a mere reflection, a simulacrum of the male without true perception and comprehension of the underlying forces at play.
Such a 'woman' is called 'slut' or 'dumb whore retard bitch' because they inherently lack that which makes the connection two men are capable of creating; the primal force, the motive, in layman's terms, a soul - in which to grind against the other, to generate the spark of intuition unknown to such creatures. This is also why the idea of two women having sex is so ridiculous; it's just velcro on velcro, all you're gonna get is friction.
