This will be a little controversial so please keep in mind this is c/nostupidquestions.
I feel like any relationship is, at its core, an agreement. An agreement between two people to spend their time, affection and dedication solely to each other. By virtue of their feelings for each other. This is normal.
However if it were truly up to me. I would just sleep with another girl every day of the week. I honestly don’t really care about spending time with her all that much. In fact, if I’m brutally honest. For me a relationship is a mean to get sex and I guess spending some time with her isn’t all that bad either. I am perfectly willing to stick to one woman. That is no problem to me whatsoever. But is this a healthy way of doing relationships?
A relationship should never be used as a means to have sex. That will only hurt people. And a relationship is so, so much more than just sex.
Honestly, to me it sounds like you don’t really want a (romantic) relationship in the first place. And that’s completely fine. Don’t try to force something on yourself that you don’t want. That will only hurt your partner and disappoint you. It’s completely fine to just want friends with benefits or one night stands (or both, as long as you’re careful). You do you.
