Why do guys always find it a massive turn on watching girls masturbate?

[Rixon]

Girls look the most vulnerable and very attractive while masturbating. Also thats something which entices the curiosity naturally so it's always a huge turn on.

I don't know what to tell u dude, it's just really fucking hot

Most men are attracted to most women, most women are only attracted to a few men. Likely that simple. Also men typically have a much higher libido than women, and are much more responsive to all kinds of sexual stimuli in general.

Because men are more visually stimulated, while women enjoy things like touch and smell more.

It is not a good look for a guy. Maybe gay men like watching other men jerk off, I really don't know.
