What's the point of looking at sexually arousing things (women, images, etc.) if you don't intend to jerk off or have sex? This sounds like a rhetorical question, but if you think about it for a while, why do we do this? You would think that if we aren't interested in jerking off or having sex, we would be able to decide to just ignore hot women (from a straight male's POV). But it seems that we lack a certain degree of autonomy when it comes to sexuality. If you're not hungry, you don't think about food. But if you're not horny, you immediately become horny when you see a big pair of tits or a butt or something. Even if you have told yourself that you will not engage with these things in any way, you still have the overwhelming desire to stare.
