I tend to find small, enclosed spaces (an being underground as well) to have a calming effect (as long as there's no crowds of people). I have a metal crate I purchased at a surplus store that I can fit into and enjoy the feeling of the closeness and the metal along my body. As a child, my love for tight, confined spaces proved useful in Hide-and-Seek. The only problem is I'd fall asleep and the others would start to get upset or panic.
I wonder if this is tied to the comfort and sense of clarity I feel wearing my body armor and while applying deep pressure to my body

(that's my curious face).
People with Claustrophilia enjoy the things you mention -- just like you do. Most will not admit publicly to the underling fact that they get sexual gratification from their fetish.
I see absolutely nothing wrong with sexual claustrophilia fetish as long as the two rules that all of the medical advice is based upon are strictly followed.
Those two rules are: 1.) Never never enclose your head or body or do anything else that will in any way restrict your easy breathing . 2.) Always always have a totally safe and easy exit and escape from such confinement or such practice.
Many deaths with heads or bodies found wrapped or fitted inside things are due to suicide/homicide -- but after investigation as to the cause of death, some are legally classified as death due to accidental sexual gratification type asphyxia (usually medically classified as: autoerotic asphyxiation).
In the USA there are a total of about 2.4 million deaths per year, but only about an average of 625 each year that are statistically classified as autoerotic asphyxiation. .
This is a hard fetish to ever change... so follow the two medical rules and just fantasize the rest. Never become a statistic. You should be just fine.
Also, a lot of highly intelligent people have had this and survived it.
