I’m assuming you find out your love language through normal convo, which will be hard cuz some of these joints will lie lol.Oh, ok, a clean slate period. I wouldn't share it at all. Id use it as one of many weeding out tools. You either find those you match with or you kim.
Either way, you're a slight bit ahead bc you may have information she does not. Thusly armed, you could either make her week by 'speaking her love language' or, conversely... you could withhold it.
It wouldn’t be smart to hit a joint with a quiz first/second date or ask what’s hers
