I'd say 3 is the perfect number in a harem, 1 girl and you'll argue, 2 and they'll argue with eachother, 3 and ya know sometimes i guess maybe one will shut the other two up or something. i feel like i had something going in but as i typed more i pulled more out of my ass so there ya go.
3 is perfect
Definitely 3 is the magic number when considering relations and content distribution or fetishes
Any less and it's "vanilla" and any more it just becomes a harem
