@AlliFlowers Well, there is no official sign for "gender" (except for finger-spelling). There's also no official sign for Mr., Ms. (finger spelling is used where specificity is req'd). - but there is a sign for Man, Woman, Girl, Boy.. and they are all different. So genders are present in ASL.
Having said that, pronouns have no gender and most often spatial indexing is used instead in my experience.
Did I misunderstand you?
