swimmable mermaid tails count as gender affirming care btw

[diadromous]

in cases you needed a reminder, it's fine to change your mind about your identity. identity is a social construct, the "rules" are entirely made up. also no one except yourself can dictate what or who you are

Hi, hello!

My name is Marin, Sy, or Siren, I'm a headmate in a system, and made this blog to (theoretically) document attempting to become a professional merman!

What is a professional merperson? (link)

I'm a mixed source headmate, being a fictive of Siren from Castle Swimmer and being an OCtive. My pronouns are He/It/They (in order of preference) or any shark/fish/water themed neos!

I'm sirenkin, merkin, sharkkin, and lots and lots of other things, I am not human!

I share this blog with my good friend blackfish (forgive him, it has no real name) who is a fellow headmate of our system! Chances are it won't make an intro and he'll just lurk around, but still nice to mention!

Oh kin userboxes how I need more </3

All NSFW/kink blogs and/or interactions will be blocked

some info!: 1) please be careful picking anything up off of a beach or in/around other water sources - you can check online what kinda creatures/flora you can expect to see in your area and if its something youre alright to mess with, both for its safety and your own. 2) be mindful when picking up shells, as sometimes they have things living in them, and sand dollars as theyre living creatures themselves - carefully return both of these to their environment undamaged if you happen upon them. 3) check the laws in your area to see if you can keep what you find - sometimes you can, sometimes you cant, sometimes it just depends on what it is! (PT in the comments!)

All my tails!

From pre transition 9 year old me to 23 year old no longer a merMAID but a merMAN(ish) me.

Starting with my first homemade tail from 2009. Unfortunately, most of the pictures and videos are lost on my old laptop harddrive (which I am looking to get a dock for) So the only picture I have is this mega blury one. I'm in the blue and silver one, my old friend in the pink. Both used the kids finis monofin. You can also see the hole mine had from using it to death.

Next, in the same pool lol, and same swimsuit because I made this one only a few weeks after that first picture, this is in 2015 when I was about 12.

Then we have my first purchased tail, Catalina sea blue by the 2 tails. I got it in late 2015, but this pic is from 2017 and you can SEE the dispair and dysphoria on my face lmao. Also the shirt to cover my chest shape rather than wearing swimwear. I was using this tail from ages 12-15ish.

Also by the 2 tails, fire coral red, which was actually my little sisters. But she decided mermaids were boring so I stole it off her. Used it from 2016ish to 2019. So around ages 13-16. By 16 my feet were barely fitting in that monofin anymore. Friend in pic (diffrent one to pink tail girl) has a suntail.

Finally! a monofin that fits! Aussie green by finfun. But the OG design before they re-made it and imo, the new one sucks. I got it in 2019, the final year of despair before I left my fuck ass high school and could FINALLY transition. I actually didn't get into a tail and swimwear from mid 2019-2023 because DYSPHOORRIIIAAAA. It took several years on T to get to a point I could be a fish again without being hyper aware of my chest and the way wet fabric sticks to your body. Pic is from 2023, post T at last. Use this one still today! From age 16 to now.

Bought in 2023, suntails deep sea blue, and on the same rocks with the same binder and choker though lol. Also got the suntails monofin for this as my old one had gotten too small for me. Still use this one too, from age 20 to now.

And finally, my big boy. Mermaid Lucias fire koi. I'm still making some ajustments to the vynil instert in the fin, the monofin is the finis wave. Bought in 2025, still using it at my now 23 years. All together thats 15 years I've been swimming in tails.

Obviusly... koi is my fav. He's huge and bright and pretty and has side fins (mf was expensive too, used my christmas gift privlliages to get it). But Aussie green has a special place in my heart for being child me's dream tail for so long. I want to get back into making tails myself, I have the skill and sweing machine for it now. I want to make all my OC's tails eventually. Once I have the time for it, I also want to do some actual good swim videos and photos in full mer-gear. Tail, acessories, leaf top (and shirtless post surgery). Want to get some webbed ears too.

Cringe culture is dead, buy/make that tail and be a fish.
