Don't box yourself out like that. A relationship is what it is and doesn't change in value when it's compared to some other relationship. If you want to be affectionate then tell him (your partner, unless you are dating the couple) you don't like that dumb rule anymore.
This sounds like a hierarchical set up where they are the primary couple and you are a satellite. Is that why you are taking a submissive approach to your relationship?
