There's nothing you ever owe anybody during sex. If you do something solely because the other person says you owe it, that's not sex — it's sexual assault. That said, it's worth spelling out a few particular things you don't owe anyone in bed. "You don’t ever owe your partner anything in bed — other than respect," Astroglide's Resident Sexologist Dr. Jessica O'Reilly tells Bustle. Unfortunately, though, we as a society tend to view sex and relationships as a barter system. Under this belief, somebody might think they owe someone sex because they support them financially. Someone else might believe they owe someone a sexual "favor" because they've gotten one.
When we operate within this framework, it takes the joy out of every interaction. Rather than us simply interacting with others in the ways we want, sex and other encounters end up feeling like a chore, since we're just doing them because we think we have to. We start to resent one another for "making" us do things, whether they've explicitly told us to or not.
There's a more fulfilling way to have relationships, one where we only do what brings us and the other person happiness. Where you say "no" to anything that's not a "hell yes." Where you never feel like you owe any of these things, because you don't.
