Thanks: Thanksgiving at the end of the sexual relationship, a very dangerous thing on the relationship.
Command: Can’t during the sexual relationship, to ask the other party, to refrain from annoying behavior, but you can talk about it later and find how to skip it.
Urgency must not rush to end the sexual relationship for any reason, because sex is not consistent with the urgency at all.
Selfishness: participation means attention to the other, you need to satiate your desire, as well as the other party.
Artificiality: the parties must show their true feelings.
