Who gives a shit about the uke being a slut no one gives a shit when the seme's sleep around. Hell plenty of BLs feature playboy Bisexual seme's sleeping with women before sleeping with the uke. One omegaverse "Kiss me Liar" even features a seme who constantly sleeps with women while the uke pines over him, and no one bats an eye, it even has a rating of 9. Yet now the uke's are sleeping with other men SUDDENLY there's a problem!
Double standards much.
