First and foremost: Anime girls, from the way they look to the way they act. I list this as a fetish because of the difference between the amount of anime girls I find attractive and the amount of flesh-and-blood women I find attractive. I can give a long, long list of anime girls, but the number of real women that I find genuinely attractive can be counted on two hands. It's actually kind of sad.
Next, women who exhibit somewhat youthful, childish or immature traits, especially personality-wise, really get me going. Particularly, I think girls who are naive and kinda immature, though happy and energetic are highly attractive. I don't mean immature in ways that are annoying or obstructive, however; rather, I mean immature in ways that are cute and endearing. This also includes women who are small or petite, to some degree.
Getting into actual sex stuff, I'm really into some weird things, few of which are... realistic, let's just say that much. I'm really into what I like to refer to as "extreme penetration", i.e. the image of something that looks like it'd be way to big to fit comfortably inside a woman entering anyway. Anal or vaginal; doesn't matter. It looks like it would be highly stimulating to any parties involved. Another thing that I'm surprisingly into is futanari. I don't like what's called "full-package futanari", i.e. a girl with a penis and testicles, though if she has a penis and a vagina, then that's totally hot, so long as she's otherwise attractive, as well. Then there's my fetish for lactation. Milk-filled boobs are really, really attractive, and the idea of sucking on them makes me salivate like a hungry dog. The last thing I'm gonna talk about is bloating and inflation. I really like seeing a woman's stomach become distended from being so full of something, usually fluids. I don't know why I find it so appealing; I just think it's really sexy.
