Ultimately, the ideaology and point behind poly (as I understand it) is honestly and upfront relationships (with however many).
The honesty and upfront part comes in to play regarding your question;
it's about stating what we want/need/expect from a relationship (both parties) and then deciding if those wants/needs/expectations are compatible.
Instead of just saying "i like you so lets go" without communicating wants/needs/expectations; like monogamy.
Therefore, you two need to do that-and clearly, this is a topic that hasn't been negotiated to both peoples satisfaction and needs addressed asap.
Personally, my answer would be daily. But, my husband, is more of a weekly kind of person (unless he's caught up in NRE, then its hourly).
