Depends on the definition, but usually, those who have at least a sexual partner (even one who is not their "true love"), they're not incels. Of course, the better way to escape the inceldom is to find a complete relationship (not just sexual one), but here we mean all of the ways, which may lead to ascending/escaping the inceldom. Let me make this analogy. If you're hungry, it's okay to escape the hunger via good lunch (soup, salad, main dish, fruit), but if you can't because you just can't have all of these but at the same time you have got, for example, an egg and a mandarine, well at least you're not starving, right?
Finding true love is the ideal variant, the ideal escaping the inceldom.
