Sex scene as character study is so good. What is your relationship to your body? What is your relationship to your partner? What lessons have you absorbed from the culture about yourself as a sexual being? How much do you have to trust someone before being comfortable with intimacy? What fears and insecurities come to the fore for you when you take your clothes off? It's so good.
How do they communicate? How do they expect others to communicate? How well do they understand their body and their own capacity for pleasure? What do they tend to do to make their partner feel comfortable? How comfortable are they showing emotion in front of others? How much insight do they have into what their own emotions mean and are connected to? What are they focused on during the encounter? How conscious are they of exchanges of power and vulnerability? very very very good
What do they assume from context and what do they know from experience? What roles are they socially expected to play vs what roles do they think they are expected to play, vs what roles do they want to play vs what roles do they actually play?
If they at any point during the encounter have the thought or emotional impulse of "how would my partner describe this to one of their friends later?", what happens? What would it mean to them to be caught in the act by a stranger? A friend? An enemy? How would they relate to catching someone else in the act?
