~Salutations~

so, does donnie dislike touch?

in the series, he is shown being fairly touchy with his siblings throughout the series, with some exceptions i will try to list now, tho not with proper episode names as i am not looking them up, sorry not sorry:

pilot episode, captured by draxum in a cacoon with mikey he's visibly uncomfortable and tries to get away

mikey's solo mission, he doesn't look at any of the and in response to a hug he pats mikey's head with a metal arm from his battle shell.

glued together, he's showing visible discomfort at being forced into close (touching) proximity of his brothers, tho that discomfort is somewhat elevated when they do a second go-round after the sticky foam ball got crushed

that time splinter caught everyone in a trap hanging in the lair (i think it's the forest survival episode?), he's, again, uncomfortable and the first to find a solution to their entrapment, be it on his phone

there's probably more, but that's what i remember from the series and spread out on about 60 episodes it's noticeable, but not a deciding factor, especially since donnie's also seen being fine with touch. now, the movie offers us even more of a look into donnie's relationship with touch. this list will include every instance presented i can think of, in no particular order.

during leo and raph's fight after they lost the key, donnie jumps on raph's back in an attempt to stop him from advancing in the fight, as mikey tries to shield leo. it's a very quick decision and doesn't seem to particularly trouble donnie.

after the kraang come through the portal and the turtles escape-pod out, mikey's panicking and grabbing cj, also causing him distress. donnie grabs mikey under his arms like a plushie and is shown to carry him until leo gets back with a panic attack and news of raph, upon which leo starts at cj with a fight in mind and donnie and mikey keep him away. again, no distress is coming off of donnie, no more than the regular situation call for (although he gets more logic-minded and quiet as the movie goes on with only small donnie moments breaking it up, which seems to be how he reacts to stress, but that'll be in another fever post)

he's touching mikey sometimes during the subway battle, but it's most likely he either didn't notice or didn't care, considering everything else happening in that fight (ps the kraang train is my favorite villainous entity in the franchise, give me more of the kraang train and i will give you my soul)

he's shown very visibly having sensory issues (very relatable) throughout the whole movie because of the kraang. not necessarily to do with touch, oh except for the part when he had to get EATEN BY THE TECHNODROME THROUGH HIS BARELY TOUCHED AT ALL SOFT SHELL which is shown to be a sensory nightmare and awful to touch and yes, i had night terrors if that, thank you very much.

at the very end, they all hug with no visible problems except for the fact that they are on staten island. that is to say, there's one important scene still, it happens before the end, but i wanted to have space to gush about it so here we go.

the famous scene of raph grabbing donnie and mikey flying through the air, yelling "don't worry donnie, it's not a hug, it's a rescue". probably the most important thing said in accordance to donnie's relationship with touch.

in my personal opinion, donnie doesn't mask (i mean look at his behavior) or if he does, he does it, rarely in public and even rarer with just his brothers. so every one of the hamato clan knows at least the most important of donnie's boundaries, especially related to the autism, as it's handled well within their family structure (both donnie's and mikey's autism is) . so, if raph calls out to him to warn about the hug he's giving donnie and treats it like a potential bad thing, there are really only two conclusions we can get to.

one, donnie doesn't like/hates physical contact. disputed by just about everything else in the show, except for the listed above exceptions.

two, donnie being open to touch or not is conditional. and considering the mentioned exceptions and raph's rescue from the movie, there's one similarity we can notice between them.

the touch affecting donnie is happening without his consent and without a form of escape.

(except for when donnie's hugged by mikey in his solo mission episode, but considering he's already kind of detached, i'm assuming he's just not up to it and so he uses his robotic extra arms to give comfort instead of ignoring his little brother which aww)

that's the uncomfortable part, the unpredictability and lack of a way to detach himself. aka, donnie's just like me for real. lmao.

donnie probably doesn't mind touch and welcomes it, but needs to be in control of the process and be able to leave if he gets overwhelmed. and his family knows that, hence raph's words in the movie that led so many people astray...

this might just be another evidence of how well donnie is written as an autistic character, both with his low empathy not being demonized and not preventing him from creating bonds (tho sometimes making it difficult) and the fact that the most common opinion of autistic people (that they hate touch, which is something a psychiatrist brought up as evidence of me not being autistic) doesn't apply to everyone.

as a summary, rottmnt donnie is probably the best version of donnie right now and he doesn't hate touching, he just has to touch on his own terms. extremely valid, extremely relatable.
