I'm self taught so I can only provide advice and my methods:

I'm not sure what program you'd use, but personally, I use Flipaclip on my phone with (clean) fingers. There is a built in frame and layering system. Once the scene is sketched, I separate the body parts of the characters into layers, It'll be easy to move them around as I make the rest of the frames, also keeping it consistent throughout as I'm manipulating the same sketch or so. Stretching, moving, bending, transforming, etc. It also helps to color code or change the opacity of some bodyparts/layers to keep track

Often times I have separate layers for the head, face, body, limbs (depends on how many), private parts, etc. Some of them get merged in the end to make more room. If it's a sketch, while I'm lining the sketch, I will merge the sketch layers as I go and then the linearts will be the separate layers leftover instead.

More about making the animation itself: Use key frames. I tend to have the sketch I started out with, and then I move those parts to make the final frame I want in the final animation, say, the dick fully penetrated or whatever.

Then I like to make two inbetweens, one for the starting frame slightly moving tha dick into it to be placed after the first frame, and one of the final frame slightly moving the dick out to be placed before that final frame. Then make a middle frame to tie those four frames together and boom. 5.

Except the minimum frames I use is like 9 or something, so that's just describing it as simple as possible. Basically fill in more blanks with more inbetweens. Squash and stretch is a good method, or making another frame based on the final one but let's say the dick pushed in more, and putting that before the final frame, to add a bit of weight/force into the thrust.

It also helps while you have the full 3 inbetweens drawn to just move maybe the head or something in the blank inbetween frames you'll draw later using it as a guideline for when you add the rest of the parts to see how smoothly it'll transition.

I'm sorry if none of this makes sense I'm trying it's easier if you see it yourself but you can ask for clarification lol

Hi fellow fan <3. Surprisingly not. I'll give you a short and long answer.
Short answer: everything

Long answer: I was mostly drawn to his character design and the art style, I mean look at it. It always seemed like such an expressive and well drawn/emotive show to me, just peep the El Tigre production art. Very fluid and action-y and original.. the designs, I love them so much.
His looks specifically, not sure where to start. I really like his voice and accent. Character voice is always a high factor for me. I like the fact he has freckles, they come off as adorable to me. And they're a great contrast to the badass scar on his face (Which is canonically self-inflicted when he was first testing out his powers.) Not very often seeing darker skinned characters with freckles as well. I enjoy how curly his hair is, that's also a nice change of pace. It makes me want to give him headpats. Then I guess I like how short he is and his proportions in general lmao
Personality? Well the fact he wants to be super macho and manly in and of itself. Especially when something contrasts that. It also gives me the impression he's fond of being control, especially in things such as age gaps or dominating villains or other people he'd get close to. But then on the opposite expectation, that also makes it better when he isn't in control or doesn't entirely consent, because he'd hate to feel weak or lose at anything. Or the fact he's easy to manipulate as much as he likes to manipulate people, or do things for money or valuables.

Tysm for the intriguing question <3

LONG ANSWER: Love Timtim. He was the one to get me into shota when I gave it a rewatch, also I kinda relate to him. Tho, not a lot of the porn interested me (which leads to making my own) but there are some neat Timmeh. I'll draw more of him sometime if I get the itch.

So he used to be my favorite shota, but then it was Dexter. And now my favorite shota is a secret 🤯🤯🤯.

Johnny is definitely a childhood fave / guilty pleasure but I really only like the first season and the reboot. I think the flash looks crusty and hilarious. So yeah my top shota wives are Manny/El Tigre, Dexter, and Timmy. I love Jimmy Two-shoes as a character but not much sexually, just felt people needed good male-focus porn of him. Yang + Yuck from Yin Yang Yo is a prime cub for me.

For video games it's the Playstation 2 big three / Playstation move heroes except I'd make them shotas lol. Maybe Maxwell and Alexander/Doppelganger from Scribblenauts too

You think just like me when I'm watching something with cute boys xdd, Love that soccer episode as well. His outfit is so cute while simultaneously fashionable.

I can see Manny having "fun" with any character in particular (except Frida 70% of the time) and love it lots. I find the background characters to be well designed and I was asked to draw em but I forgot, but this sure as hell inspires me to xp

I'm very partial to him with characters bigger than him, so maybe along with that blonde fella I'd like to picture him with the big kid... but overall, him having a gangbang with the team is a thought that gets me going right now. I always think, considering he doesn't have a secret identity, how many yearn for the day to put the mighty Manny Rivera "El Tigre" in his place, show him he's not all that xb (I have a thing for dominating superhero shotas)

Sorry for the late answer, + Fellow brainrot? 👀
