Sounds like you have a very clever little boy.
There are some things that stand out as characteristics of autism/aspergers. If your child had no speech delay/problems then they usually look at the criteria for Aspergers. If you son had language problems eg. not understanding/misuse of pronouns, echolalia (repeating TV/DVD speech or repeating words/phrases spoken by people). To find out about echolalia google 'delayed echolalia' and read about it. "I did it" and "what's that noise", could have been echolalic repetitions of phrases he has heard before.
Your son does sound like he has alot of sensory things going on. Again, if you google 'Olga Bogdashina' you will find an article about sensory differences in Autism Tody. She has also written alot of books and the Autism Department in our area invited her to come and speak to professionals and parents. But basically all of their senses can be oversensitive or undersenstive, and the 'level they perceive things' can alter day to day and throughout the day. They can also have problems 'interpreting' what their senses are telling them.
Your son sounds very light sensitive. My son too would always want his hood up/cap on. Curtains had to be drawn in the house etc. Look up 'Irlen Syndrome'. This is a visual perception difficulty experienced by many people including those with dyslexia and autism.
Autistic children are usually very good at visual/spatial things eg. puzzles/model making. Some children almost teach themselves to read and write.
They can also be very good at language (speaking it), but may not understand what is being said to the same degree eg. my son is assessed at age 7 (he is 7 years old) for expressive speech and age 3 for receptive speech. They also tend to communicate only for their needs to be met eg. I want a drink, put the TV on etc. They don't know how to use social 'chat'.
The things you call OCD traits are usually described under autism as 'rigid behaviours and set routines'. So your son has learnt to do something in a certain way and if it is done differently it will upset him because, from his point of view, it is 'different' and therefore 'not the same thing'. From a communication point of view he may have learnt how to say 'hi' to someone first, then they reply, then he knows what he says next. If that order is changed and the other person starts the conversation with 'hi' he no longer has his routine to follow. Does that make sense. You could practice with him so that he learns how to respond to someone saying hi, but he is still very young and he may simply want to keep to the set format for the time being.
Hand flapping and spinning is very common in autism and it usually shows itself when the child becomes excited/stressed etc.
having meltdowns. Autistic children can have problems understanding where they end and another person begins. They also have difficulty understanding that you cannot read their mind. Again he is only 3+ from a developmental point of view. But he may get upset because you have interupted the routine (or another child has). Or it may be that you are asking him to stop doing something and he has difficulties leaving things 'unfinished'. It could also be the 'unpredictability' of social interactions that upset him. Autistic children tend to 'rote learn' responses and find it very hard to 'think on the hoof'.
Wrapping him in the towel could be a sensory thing. Many autistic children like deep/firm pressure. It will make him feel calm and safe. The sensation of water on his skin maybe distressing him. My son is hypersensitive on his hair/head/ears/feet/nails. Getting his hair cut used to be a nightmare. We had to leave once with half a haircut because he was so upset. He said it was hurting him and it was. So I just found another gentler hairdresser. With sensory issues you have to try to understand how they are 'feeling' it. Even if it doesn't look painful to you doesn't mean it isn't painful to them. Your son may also be undersensitive to things eg. he might hurt himself and not feel a thing.
If you find out more about autism you will understand more about where some of the fears come from. The shower: is it the sound of the water upsetting him (auditory oversensitivity) or is it the feeling of the water on his body (tactile sensitivity), or is it that you don't have a set 'shower routine' and he is afraid of the unpredictability of it.
My son was also afraid of talking toys. We had to get them out the house. For my son it was that they talked unpredictably. So he might be concentrating on doing a puzzle and then Shrek would say something. It would (a) scare him because of the sudden voice out of nowhere and (b) it also destroyed his sequence in the puzzle and he might lose his place and have to start again.
Liking his blankets/fabrics etc could be a tactile thing.
Children on the spectrum also tend to be later at certain milestones, especially potty training, physical abilities etc.
If you are at all concerned, which I can see you are, then I would go and seek professional advice.
From age 3+ children start to become more social and it is usually around this age that alot of autistic/aspergers children are picked up because they simply cannot cope in nursery because of the social demands placed on them. So I would start the process now, so that any therapies can be started and be in place prior to starting school.
Google Sensory Integration Dysfunction and see if it fits. There are therapies that can be done for him at Occupational Therapy - like "brushing" that will help reduce his tactile defensiveness.
Best wishes.
