this thing is simple: girls love pictures. take a cute picture of her, then move close to show it to her….while she’s staring at the picture, look at her. if she reciprocates the energy,keep looking at her as the tension builds ,then you ask, “can i?” if she nods, then you can proceed to kiss her. if she doesn’t stop you, then you have the floor.
just remember that consent and mutual interest are what matter most.
