Because I see so many possessive/jealous klance headcanons and i am not about that life:

• Keith and Lance are that couple who never get jealous. ever.
• they trust each other completely and are good at communication (partially because Keith tends to just say anything that’s on his mind so it’s hard for them to not end up talking things out)
• They check out guys together
• Shiro: *walks into the room*
  Keith: Since when is this okay the fuck
  Lance: I know.  I know
• Hunk: *exists*
  Lance: Do you ever just…feel yourself getting gayer?
  Keith: literally all the time
• Lance still flirts with girls because it’s fun and that’s just how he is
• Keith absolutely does not mind. in fact it’s kinda funny
• also always ends up with Lance in his lap no matter how it turns out with the girl
• If she shuts him down he laughs it off, chats with her like a normal person for a while, then wanders back to try the same awful line on Keith (and it’s sad how often it works)
• however if she reciprocates Lance will be back even faster to shove his bright red face into Keith’s shoulder, whining because no matter how many times he gets flirted with he still never gets used to it
• They might end up in an open relationship someday, or they might not, but they always know that they’re both in this for the long haul and no other person will change that
