What does lowering your standards mean?

Is it referring to social status? Money? Or appearance?

If it’s referring to appearance, I genuinely don’t understand what it means. If you’re not attracted to someone, you’re not attracted to them…right?

When people say things like “lower your standards” it suggests we are in control of our sexual attraction and just purposely holding back for some reason or another…

Or it suggests that we have some level of attraction to the people that aren’t our type and are lying to ourselves about having it, out of stubbornness.

So what do people really mean when they say this? What part of that is within our control? Again this is NOT a rant or anything of the sort, I am genuinely just a clueless girl confused by this phrase lol
