Everyone goes through the casual dating phase before taking things further and getting into serious commitments and this is the phase where a couple gets to know about each other deeply in every possible way. Every person likes getting into this casual dating except the ones who love one night stands more than anything else. Casual dating is not at all casual and indeed it must be taken seriously if you want to get into a serious relationship with any person. Just because the phrase sounds casual, you must not take it casually, especially when you are dealing with a demisexual person!
Having demisexuality as a sub orientation, a person only opens up further with another person with whom he/she feels comfortable, trustworthy, and emotionally connected and all of this happens only through casual dating because the concept of sex is null in the aspect of casual dating. And there are many more aspects, a person needs to focus on to get through this face to witness the further intensity of a relationship.
