A little boost
Dude has a weak personality, or so he says. He said that his wife is disappointed with him although she’s not saying it out loud. It is obvious with the way she regards him, especially when they are alone in bed already. Clearly, dude needs a testosterone booster. Something to boost his confidence in every little thing he does.
He was used to being belittled when he was a kid. His stepmom was a monster. I think Dude brought it with him. I do believe he will be able to let it go if he just gets a little boost to his ego.
