And I don't understand it.It's simple: boredum and variety are two things people want. Having sex with the same person day in and day out, year after year forever is just.....not mentally feasible for a lot of people. Physically even.
I don't understand how people get sexually bored of their partner, unless they were really desperate about who they got with in the first place, and "just settled," instead of waiting for what they actually wanted.
But in that case, it would make more sense to not get into a relationship at all.
I also don't understand sexual attraction without romantic attraction. It's just such a weird, kind of gross concept to me.
