I'm not Mirzhan_Irkegulov, but my reaction to the two is very similar: both are correct, and in general no one has an obligation to have sex with anyone else and no one has an obligation to employ anyone else
I'm not VoiceOfRa, but I'd like to throw a little twist into this comparison. Let's change from "no woman owes sex" : "no boss owes a job" to "a women has the right to withdraw consent to sex at any time" : "a boss has the right to fire anyone at any time". Still very similar?
"a boss has the right to fire anyone at any time"
In the US that's already the case and even the people who don't think that wives should be allowed to refuse sex from husbands seem to see nothing wrong with that. Well, except when someone is fired is for saying something factually correct but offensive.
Speaking from personal experience, finding the right relationship can be HARD. I recently came across a rational take on finding relationship partners, much of which really resonated with my experiences:

(I'm still working my way through the Sequences, and lw has more than eight thousand articles with "relationship" in them. I'm not promising the linked articles include unique information)
