I seem to enjoy certain types of digestion and vore, presumably because like pregnancy, they involve something uncontrollable going on inside the woman's vulnerable belly.

One thing that I have found to be an interest of mine, while a woman is pregnant, is hairy pussy. Some women prefer not to shave because of how difficult it gets and honestly I've always felt like hair is the mark of a woman. Other than that the other fetishes I have are for MILFs, squirters, and role play where a woman is in charge (boss/secretary) and when you add pregnancy to that mix it only gets better.

Gyno/Medical for me(Pregnancy themed)

First time noticing this thread now it's popped back up. Interesting kinks some of y'all have. I'm surprised more people didn't say stuffed/bloated/inflated gals since some of 'em can go from flat bellied to looking 9 months along. That's hot af to me.
In a similar vain, a loud sloshy belly can be attractive. Who wouldn't wanna fill their girl with water 'till she looks pregnant and both hear & feel from inside all the sloshing..?
I expect lactation goes without saying.
Recently found from rping with a lovely lil' sub. I might just be a bit of a sadistic Dom. Quite like the idea of squishing a gal under my weight. But who would dislike the idea of their partner doing anything to please you no matter how roughly you use their body..?
And I kinda get it with cervix play. It's an incredibly private thing to show someone let alone let someone play with. Although I wouldn't want to take that kinda thing too far since inserting things like marbles or beads would probably be harmful realistically.
Massive insertions can be very hot if not simply impressive. Pussy, ass, or throat, they're all impressive and hot for different reasons.
Can't think of any other fetishes, although there's always room for fantasies within them to spice it up. Even if y'all don't wanna share your kinks, hope reading all these freaky interests makes you a little more confident with your own freaky interests, cause in the end all you can do about it is laugh!

MILF
Breastfeeding
Femdom (gentle femdom included)
"Reverse" Rape
Mother/son incest
Older sister/younger brother incest
Teacher(F)/student(M)
Basically any older woman/younger boy dynamic, or gender role reversal dynamic

Love vore, WG, expansion, etc etc etc

oddly, i never responded to this thread, even with my old deleted account from years ago..

some other fetishes for me are skinny girls belly stuffing/overeating/bloating (i'm a big Little Eater C4S fan, she's the pinnacle), some ageplay (though not into the DD/LG stuff, it creeps me out), belly inflation/enema play, skinny women (bordering on ana), women smoking (cigarettes or weed) or drinking while very pregnant, some light bondage, belly fetishism in general (enemas, inflation, some vore), cumflation, belly bulging on skinny women (from cocks, fisting, etc.), select models from the 90's big tit heyday (tiffany towers, wendy whoppers, letha weapons), goth/metal girls with tattoos, huge insertions (jayda diamond, samantha luvcox), etc...

a lot of overlap with pregnancy fetishism, because i've had a belly fetish going back to when i was a preteen.

Well the most common ones that's usually associated with the pregnancy fetish are: vore, hyper pregnancy, alien pregnancy, stuffing that's suppose to give you a pregnant belly egg laying where the woman is the host. Others are: mom-son incest, brother sister incest (that one can go either way but mostly older sister and younger brother or older brother and sister who is a few years younger than him), MILF but that can go with family incest as well, teacher-student ( that can between female teacher and male student or male teacher and female student). those are the ones I think are the most and second most common themes with pregnancy. MILF, Incest and Pregnancy usually tie into one another in certain ways and are very popular.

I'm surprised I never saw this thread come up before, but will add mines into the mix now.

Other than pregnancy the only other fetishes I have are for;

Sister-Brother Twincest
Amputees

I loved looking at Anime when I was 'discovering' and that led to hentai, etc, and I found the pregnancy side of things, but also found the kinda more violent side of things, (i.e. anime strips with people getting limbs cut off) and both kinda snowballed from there. My pregnancy fetish is my #1, but there are occasions where both my pregnancy fetish and amputee fetish combine.

I like big bellys. Can appreciate body inflation, ams like breast stuff. I also really like the whole like inflqting a balloon under a shirt, or like huge huge balloon belly and boobs.
