Because you said it’s objectifying yourself? And that’s not a good thing? And saying you’re not that interested in romance is very different from “I would rather be alone than being with a person who just finds my body good enough“. That means you’re interested, as long as the other person finds your body very attractive.
Again, define “not attractive”. Because ugly and fat characters are almost always made fun of. If “not ugly, but not gorgeous” characters count as “not attractive” I can find a lot of female ones too.
