@Riot: How often will you be using sex as a plot device?

Miss Fortune's had many lovers in her career, Ahri's a gumiho (so it's a given with her), there's no end to the rumors between Garen and Katarina, and it was even hinted that Illaoi probably slept with Gangplank at least once. As such, we know Riot's not afraid to get a bit raunchy when needed.

But will these "raunchy references" be more common in lore, or will they be rare? For instance, will Janna have a bit more promiscuity in her background, or is that too dirty?

No need for explicit lemon scenes, but some subtle innuendo will definitely suffice.
