Make sure that everyone is actually interested in it and not a “for you” kinda thing. Like make sure the females are as hot for each other as you are for them (or whatever the gender/person setup is).

Also, wait a week. Actually contemplate if this is purely for your satisfaction, or something everyone wants. If it’s a “gotta happen right now”, don’t do it in a relationship. If it’s a hook-up, use your own discretion as you probably already do with partners.
