need help!!!

so i was reading this bl manga but i’ve missed it and i also forgot it’s name(fyi i suck at explaining so bear with me)…the first one is about these magicians(they stay in another world i think)that need humans to strengthen their powers and they can summon humans legally but the ml the seme with white neck long half hair summoned the mc which is black haired illegally but initially the guy summoned the mc’s little sister but he interfered and go summoned instead. the second manga is the mc is black haired(seme) and he is younger and the ml is white haired or blonde(uke) and he’s older and they are currently married i think..the only explanation i can give is that they just have funny misunderstandings and are sex maniac, the uke once thought he wasn’t sexy enough and thats why the seme didn’t want to sleep with him anymore so he went to the gym to work more on his boobs and assmeanwhile the seme was thinking the uke thought he liked sex too much so he was cutting down on it. si olease if anyone knows olease do tell me me(づ￣ ³￣)づ
