Indeed, two people satisfying their respective needs. Personally speaking, I sometimes worry though that what starts as a simple functional arrangement might in the end be more to one or the other person - and the process of resolving this when there really is no long term basis can be painful. Is it justifiable hurting another person for personal satisfaction or materialistic gain? Maybe is if you are blatant enough about it and it makes you happy at least for a while. Thanks for your upbeat message - helps me to stop being so fussy and worried.
