Recently, I've noticed that I haven't been as turned on by pregnant women as I used to be. Whereas before, I couldn't even see a pregnant women without getting turned on at least a little. Nowadays, it's just awkward to be around them. I'm not turned on or anything, just a little embarrassed. Also, I've noticed that I've gotten more turned on by "normal" things, like asses and boobs, than the pregnant bellies. Personally, I think I'm just getting out of my pregnancy fetish stage in life (I'm 17). That, or it's simply an environmental thing, whereas the more I'm exposed to "normal" fetishes (cleavage, asses, etc.), the less I get turned on by pregnant women. Any thoughts on what's going on with me?

in your age, it's very common. Our "subconcious desire" my keep changing by it's nature due to it's curiousity and the hunger to "new things".
Some parts of it may stand on the same categories and some other parts may turn to the other. After lots of knowing, experiences, and maturation, this subconcious desire will be content.

In my case :
about 9 yo, turned on by big boobies, "like to see" preggos but without turned on.
14 yo, love skinnies young girls, big boobies, started turned on by preggos.
17 to early 20th, dislike skinnies, turned to a bit chubby type, big boobies is the top priority, started to awares to big ass, started to worshipping preggos.
mid 20 to late 20, started to like lactating, totally turned off by skinnies woman, young age is not an important thing anymore, but love more mature women like 23-30 yo, big ass is now my 2nd priority of beauty & sexuality, boobs is 3rd on that list, PREGNANT is my top list.

Now, my desire had stand on it's ground :
a late term, curvy body, about 23-30 yo preggo with firm big ass and big boobies, spraying milks on me while we fuck.

Interesting. For me, my pregnancy attraction has remained pretty consistent throughout my early teens to adulthood so far(I'm in my early 30's). Though asses(women's obviously) are just as much a turn on too.

I have to admit that last few years kind of dulled my prego fetish. Back in time Ive started collecting prego vids because they were so rare. Now there are prego models everywhere, but 99% of vids hardly feature any action worth the time and HDD space not even to mention money.

Stable for me, but sometimes I focus on other things (massive breasts, massive butts, whatever).

I don't collect pics from the Internet at nearly the same rate I used to 5-10 years ago, for a number of reasons. But my overall fetish hasn't really waned, and my heartbeat still increases when I see a preggo in public.

Something that is not often communicated is that sexuality, like everything else in life, is a fluid thing. It's totally normal and healthy to start liking different things
