if anyones curious as to why sometimes they can touch eachothers clothes and sometimes not, think of the holy element(aura) like a thin film around a person that hugs the person's body, kinda like a toilet paper mummy if you get what im saying, so even if safi touches Shibuki's gloves or tip of his shirt technically her film like auras not coming into contact with Shibuki's person. So condom jokes have no relevance
