Maybe i don't remember it exactly but my problem with that scene was different. It felt too robotic. Like "Oh btw idc about your junk, i'm ace", "oh ok".
Like in real life that's not what happens.. Something like cooper joking he's just lying because he wants to see him naked is way more realistic.
It also confuses the audience a bit. In the same minute, we are told the mc is asexual, meaning we probably won't get lewd scenes because asexuality usually means you don't like sex, but in the same second we see cooper's junk.
So like.. a bit confusing.
