Claustrophilia
From wipipedia.org
Claustrophilia is a love of being in a confined space, which is the opposite of claustophobia.
People with claustrophilia are likely to enjoy wearing hoods or gas masks, all-covering skin-tight clothing such as catsuits, heavy rubber, strict bondage, coffins and total enclosure fetishism.
People with claustrophilia need not be sufferers from agoraphobia.
