OK I’m really not a sexual person but I seem to have found inspiration in Grillems - hope I didn’t disappoint :)
Who is louder? James motherfucking Willems. He will literally not shut up, and the neighbors would complain but they’re Bruce’s old lady friends and they’ll always just wink at Bruce in the hall after a particularly wild night. Bruce is almost completely silent, but sometimes Bruce will softly grunt when he comes. James is in love with that sound.
Who is more experimental? James, surprising to no one. What is surprising is that he’ll actually get embarrassed when he brings up ideas to Bruce. Bruce is so distracted by James’s adorable blush and body language that he automatically agrees to anything he says. James forces him to have an actual conversation about it.
Who takes more risks? James - he’s spontaneous about it, which leads to the only times Bruce will speak up during sex. “Are you sure you’re okay with this?” “It’s my idea, Bruce!” “Okay. Just tell me if you want to stop.” “I’m gonna fuckin stop if you keep asking me!”
Lights on or off? It’s a mix - neither of them really care, but they end up on most of the time. James loves positions where he can watch Bruce’s face while they have sex. Bruce is constantly aware that James has the body and face of a Greek god. Once just looking into James’s eyes after sex got Bruce hard again. It was a magical moment.
Who is more likely to be caught masturbating? James. He’s the most sexual person Bruce has ever met, and even when they’re having sex more than once a day, every day, he’ll walk in on James jerkin’ it. “Jesus James!” “Oh Bruce! Come join me!” James feels no shame about it.
Who comes first? Bruce, even though he’s all about James coming. He’s never let James go unsatisfied, not that it’s usually a problem.
Who is better at oral and who prefers it? This works out perfectly because James likes to give head and Bruce likes to receive it, and they’re both uncomfortable enough with the reverse that they’ve never even tried it.
Who is more submissive? James. It surprises Bruce the first time they have sex, because of James’s personality and how he crawls all over Bruce when they make out. James loves to just be ravished in bed, and Bruce will come first because he gets off on James’s pleasure. Sometimes just thinking about James panting and begging “uh- Bruce please,” will give Bruce an uncomfortable boner at work.
Who usually initiates things? James always has to. Bruce will never initiate sex is because once in a while James will go through an endorphin crash and Bruce feels really guilty, but he feels better knowing that James wants it and had some control.
Who is more sensitive? Bruce is typically not, but once in a while James will discover something that drives Bruce absolutely nuts. Bruce goes to the moon when James kisses his earlobes. James is more sensitive - get him at the right time, and every inch of his body is an erogenous zone.
