BJ Alex was his sexual awakening and then Jiwon was his first real sexual encounter and also his first relationship. You only realise your power through experience, or if your partner makes it clear that you have power over them. DG is building experience and slowly realising his power, even though his development is realistically slow and sometimes painful to witness.
Something that has always bothered me about this manwha is the fact that DG doesnt realize how much power he has in this relationship.
