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?
Sounds like you value alone time and independence but also want some sex - even just casual sex. Honestly, I don’t see a problem with that on the surface; just because the norm is committed, heterosexual, monogamous, cisgender, same-race relationships doesn’t mean everyone has to follow that, so long as your boundaries (and theirs) are clear and agreed upon with anyone you get involved with. You may have a hard time finding someone looking for something similar, but that doesn’t mean you’re doing anything wrong - just different.
The one thing I’d watch for is making sure you don’t see women as a source of sex and that’s it. Not saying you would, but what you describe COULD be a starting point for that kind of mentality, which is not a good place to be.
