While it's true that comitment is not necesary to have strong feelings I do consider comitment important for my relationships.
As for the rest, my premise is simple: so long as all the parties involved in a relationshipare informed about all the implications of the relationship and are consenting, it's ok.
In my relationship I require a lot from the other party(ies) (in plural as my ideal relationship would be to have two female bisexuals that are couple as my partners) and it includes comitment understood as no flirting, no sexual intercourse with others, no sexual interest in others, no erotic interest in or contact with others, no greater intimacy with others than the one had with me, being willing to spend 1,440 minutes a day with me and unable to spend less than 960, no secrets. And all this not as something forced upon them or accepted forcibly and/or as part of a negotiation but because so they enjoy and want it, otherwise it's undesirable for me.
As for hugging and even kissing on the cheek, that's fine by me.
