Vorephilia is a rare philia (okay, genius, I know) which makes you get reeeaaaally damned hot by seeing/imagining something related to a life form being eaten alive. There are people who feel more excitated about both being eaten (preys, in related jargon), being the one eating (preds), or just seeing it in third person (dk).
There's a lot of art made by voreaphiles about practically everything you can imagine but plenty of voreaphile people notice the thing while seeing weird things in youtube or watching a film's special effects (I got a boner while seeing MIB when I didn't even know what was a boner. I asked my father if that meant I was a alien >.<).
For practically all 'preys', being eaten by a snake is like, I dunno, maybe having a threesome with the two hottest girls in the world, later the 'it implies dying' thing comes up, more strongly when you realize that the snake would surely kill you BEFORE swallowing you (yes, that feels like real shit when you first know about it) but we preys are, in survival terms, lucky that snakes are far from the medium man, otherwise maybe some of us would have been diggested by now and if other preys are as sweet and nice as I am, that would have been a shame =^w^=
(if you are casually wondering what it feels to like seeing an animal die in 'hands' of an african rock python, or even have the awfuller death ever being diggested alive; You feel fucking heartless. It's hard to get used to it.)
(also, at least for me, it's been a problem with the couple thing, I'm almost an adult and I found myself some months ago doubting about my own sexuality because I had practically never looked at normal porn or interested the way some people describe in women, but as the gender is not decisive in swallowing, some of you could get really disturbed if I uploaded some things that I found damn hot when I first saw them. Seriously, my libido is so fucked up that everytime I see both normal porn or vore I start arguing myself about if that's hot for my natural unsconscius mind or if I've alienated it so much that it no longer can identify real subjective hottness and I should never look at it again, preventing me from being relaxed enought to get hot. Shit, I've a problem, plz if anyone of you have lived this, answer me.)
