One day Finn catches Poe shaving his legs. Poe explains he likes the feeling every so often, so he does it occasionally (generally after really long periods stuck in a cockpit and a sweaty flightsuit).

Finn finds he also likes the feeling of Poe’s freshly shaved legs. Maybe he helps Poe shave them next time, or tries shaving his own legs.

If Rey is in the relationship, can she not be interested in shaving her legs?
