What do I roll for seduction?

I plan to play a bard who is very seductive, somewhat of a Casanova. Do I roll persuasion, performance or some other skill check to determinate the outcome?

Our game is less dungeon-delving and more social situations, so I expect this to come up often enough. Usually our group just roleplays seduction attempts but this PC is very promiscuous and I don’t feel like roleplaying it out every time my character tries to seduce an NPC. It would become awkward for me, the DM, and the rest of the group. So I’m looking for a rule I can fall back on.
