I'm pretty open in this regard! Though I do have some slight preferences. With regards to vorish scenarios, in order from most liked to least, my preferences with regards to gender in vore go something like this:
1. F/F 2. M/F 3. M/M or F/M
But that really doesn't mean that I dislike any of those combinations! I end up drawing a lot of F/F because that's my top-tier preference (and if I'm putting in the effort, why not draw what I like the most?), but there are a lot of interesting scenarios to be had with males, too! And honestly, the gender doesn't always matter that much. My drawings and stories are rarely sexual (and even if there are sexual themes, they're never explicit), and most of the interest for me comes from different possible relationships between predator and prey, or the different ways their personalities collide. Those kinds of things can vary wildly, regardless of gender!
In addition, I'll add that my interests are pretty varied with regards to body types, too. Skinny, chubby, muscular, etc can all be appealing to me, on both males and females. I've been trying lately to get better at drawing a wider range of body types, but of course it's a slow path to improvement. (I do have a soft spot for size difference between pred and prey, though, with the pred being significantly larger; it plays into the themes of control/domination that exist in a lot of my stories.)
