They took those photos for the sole purpose of making you masturbate to them, thus losing valuable minerals in your body. Every cumshot is equal to a loss of zinc, a mineral that your body REQUIRES for organs to function properly. Candid pictures/videos are taken without their consent, therefore they don't benefit from you becoming weak. Masturbating to candid videos/pictures is HEALTHY.
It could be like having sex with a succubus who will steal your soul away. She looks very desirable but her heart is made of ice and her very touch is death. Then as an undead you will walk the earth only outwardly resembling a living human being. Your purpose only to spread the disease and encloak others in the same kind of darkness that has enveloped you.
Death is very desirable but people only realise this when they encounter it at last. To men she comes as female, slightly androgynous but perfect of shape and form. Those who could see clearly would scream with fear at that moment but conveniently lust clouds their vision. And when she finally takes them into her embrace, it's the most ecstatic moment in their lives and also the final one.
Not all of them. The last girl I interacted with was quite cold. Her beauty was extraordinary though. Not that I expected her to feel anything for me but how heartless she was surprised me. Luckily I didn't feel much for her either. In the end her beauty was eternal, immortalized. Her skin had adopted a slightly grayish tone, and the tiny blonde hairs reflected the sunlight coming in from the windows. Her eyes were looking at the ceiling without seeing anything, so I shut them for her when I left.
On a serious note, some girls like to pull that "I'm way out of your league" play to see how you react, if you are a chump you'll go along with it, I usually act put off by her behaviour and she's back to being a worthless dick-hungry attention seeking dog in a moment.
