Yes!! Sex work exists and while controversial for a number of reasons, I'm not gonna shame someone for doing it. I just tend to be weary of romance media where one of the partners is a sex worker, cause I get very put off by the idea of sharing one's body and pleasure in that way while in a romantic relationship with someone else.
Just a personal preference and even still, I have favourite stories which include this line of work (like Pink Heart Jam). So I was really happy we didn't see him with anybody else here!

Usually i'm not into sex worker uke or seme but this one is good, glad that author didn't show uke or seme have sex with other ppl
I mean we all know seme have sex with other ppl, but it's not necessary to show (thanks author sama)
