It's interesting to see how many aspies enjoy the feeling of hot water. I love it too, feeling hot or warm water on my skin. I love the touch of the water running on my skin, especially on my back. I also like feeling the pressure of water on my body during baths or swims. I've always had a fascination with water, with the way it looks, moves, runs, leaks, feels etc. When I was a kid, whenever I had to stay at some relative's house for a few days while my parents were away, my mother would tell them that if I was upset or bored or something they could just put me in a bath and I'd be happy in there for hours.
I also enjoy certain kinds of touch on my back or head, kind of like being petted like an animal.
I like repeating the same songs over and over and sometimes I even repeat just some specific part of a song. I do this to movies and TV shows too, watch a short part of some scenes repeatedly.
I like certain smells a lot. If I use a perfume or a soap that smells really good to me or if I pet a dog, I keep sniffing my hands/skin/clothes to smell it.
I love touching things that are really soft, like certain fabrics or animals.
I like colorful lights like Christmas lights, so I keep them up like half of the year. I enjoy the mild, colorful light from them.
