Well, glad I could catch somebody's interest about that, in a way !
But sadly, I don't have photos or videos to share yet...I'd sure try to work on these things though, even though I'm a straight guy, I guess we could find a way to gather common sources to be turned on ^^
The best I could share so far is mostly crying discussion, so until I'd get some news then, I wish you a wonderful day and good luck to find something to feed this marvellous forum, as I'm sure we're all trying to and hope to achieve in one way or another ;)
 

I felt like I needed to share this :
My second fetish is far less difficult to achieve than the "main" one, but both of them are at least either old each other as long as I can remember...so yeah, I also have a kink for women's lower bellies and navels at the same time.
However, I only like it when it looks like very specific shapes. Basically, the longer lower belly is the more I like it, which means the navel should be closer to the chest than the vagina in standing position. In other words, we could also tell I like high belly buttons. Speaking of navels, I only like them too when it's innie and deep enough so we couldn't see the skin inside of it, like a dark hole, you know...my favorites shapes are those which have a half a circle at the top of it, but besides that, it can takes a lot of shapes that I can find amazing ! I like girls with curvy or chubby lower bellies, but not muscled, skinny or over-fat ones though...
The best part about that is probably when my two different fetishes can combine with each other, so the most obvious example to give is when a shaped woman as I like cries and drops tears in her navel and then trickles down all over her lower belly (better again if she's only wearing very low rise panties while doing it)...!
So yeah, that's a thing, but then again from my point of view of course ;)

Indeed, I confirm you it's hard to achieve because I never really could see that happening...completely.
Yet I remember very quick moments I already witnessed in my life such as seeing an elder cousin of mine shedding tears on his naked belly when we were children, between 7 and 10 years old I'd say, and that triggered me enough to still being turn on by falling and trickling tears over some surfaces, whatever it can be...also at school, some very uncommon times, I saw girls in my classrooms, maybe 2 or 3 in total during my 10 main school years, letting their tears fall on their desk, but they were not my table-neighbours so I couldn't manage to see precisely enough the impact it had over it and it never last long anyway. The first time I noticed it, I was 11, second time I was 16 and the last time I was 17. First time was too distant and unprecise I don't have enough details about it, the second I remember one of our teachers noticed her sheet had water over it when he gathered everybody's sheets and the third I could see her behind me when I just turned back to watch her cry and she was letting her tears drop silently on her arm, between her wrist and her elbow...maybe the sexiest thing I've ever seen in a classroom ! Another time, at refectory, much younger this time I was 10, there was a girl one year older than me I also witnessed crying, silently too, with tears trickling on her nose.
When I became a student, I tried to find college girls able to cry on command and it was a total fail ! The better I could find was only one of them who just tried to do it by cutting onions and it worked a little though, but not that great or at least not as much as I hoped it would...and I mean making a full, compact puddle of tears on a table, once again of course. It was uncomplete and not large enough to consider it like a puddle, because she didn't do with real emotions so I think this why it looked like a bit disappointing.
So yeah, that would be one of my greatest fetishe
