Armomantic sims can’t woohoo?

So you can make sims aromantic but they also have to be asexual because you can’t JUST woohoo. I’m confused why it’s set up that way. Like the love bar has to be full in order for woohoo to happen. Just seems like a great big hole in the new sexual orientation area. It even has the options “interested in woohoo with” and “romantically attracted to”.
