In Limboism, a man or a woman aren't allowed to have sex, same can be said for two men and two women too. (Alongside them getting castrated pretty much.) Sex is seen as really overhyped to Limboists, Limboists mostly likes giving each other presents, gifts and making friends. All Limboists also wear a shell that covers their legs to their arms, so you'll only see their hands and feet. (Some Limboists wear gloves but that's optional.)
