Total Enclosure Fetishism
A sexual paraphilia in which arousal occurs from having the entire body enclosed in a certain way. Such methods include wearing a rubber full-body suit, being in a vacuum bed and having all the air sucked out, or completely wrapping oneself in a blanket. This practice can be carried out during BDSM.
We found him completely wrapped up in a blanket again, and suspect him to have total enclosure fetishism.
