*pokes the poll* This is one of those where a "check the option that apply" would be good.
Personally, i do have an odd interest as far as this stuff is concerned. I'm not into yiff, but i somehow found a way to enjoy this.
I kinda go by the "logic" that those parts down there are usually kept rather hidden and protected, and that most males tend to care about them quite a bit. So if i go down there, i'm going to likely get the same protection and be kept as hidden and comfy and all as the creature's member.
So i'm pretty happy and willing to climb into a creature's sheath or slit just to hide there, possibly snuggle against their member as long as it stays mostly soft and comfy...
As far as actual cock vore goes, i prefer when it's only going in by there to a different chamber inside the predator's body made for vore purposes, or going into their balls after they have been emptied out. I don't really like the whole slimy, wet, cum-covered side of the thing.
So as far as parts i like the most...
Anticipation is kinda nice. I like it when it's more as a way to let me "explore" on the outside, in a reassuring way. I like when the predator can be kinda... "casually" turned on, or simply not affected too much. The whole "i'm horny and i have to satisfy myself" thing makes me lose interest. But just doing it to show off those parts, letting me crawl around and climb along them and such while mini-sized is something i do like. It feels like being allowed to just pet what would normally be a horrible, nasty thing. And there's that quite a few creatures are rather creative when it comes to how those parts are made.
Things like the pred's cock being prehensile, or having parts of it they can actually control is very fun in my opinion. Making it feel more like playing with an odd fleshy snake than a sexual thing.
The trip in and down are fun as well, especially when there's unusual "plumbing" to explore down there. Traveling to other areas, without necessarily getting into them is always interesting.
There's also that on the way in and out, having the predator paw off while stretched out along the inside of their member does end up a full body massage as well. Well, as long as i can get out or down in a safe spot before other fluids start coming out.
Being held somewhere inside their body is always nice too. I'm definitively not in favor of being turned into something else, i just want to have a comfy hidden spot to curl up in and nap.
The "next room" can be interesting as well, as long as it's somewhere where i'd want to be. A fun idea with this part is having another creature try to get me out of there by various means... That way the predator i'm inside of can have fun, and i get an interesting ride with another comfy spot at the end.
... the problem in my case is finding a predator that doesn't mind just playing without putting the focus on the yiffy, messy aspects of it. I can be flexible, but my interest remains in the hiding spot side of it, not the sexual one.
And whee, another quick reply that exploded into a page of text.
