Those are non-sexual methods but let's be real, he could just rub one out too... It's not like he likes cuddling or anything, he just wants to get off so he can sleep and if it was the exercise he needed then regular exercise would do just fine. Honestly I think it's very silly
Even if he has crazy inSoMNiA, it doesn't just give him an excuse to fuck around lmao, drink like relaxing tea or like exercise till you drop maybe
