Resolution: the concept of fuckbuddies has come up more than once. Kind of a crude name for the concept, but essentially we're talking about a friend who is amenable to sexplay, but isn't looking to get involved in a relationship.
(Bear in mind that we are talking responsible and consensual sexplay here.)
Is this a good idea? On one hand, there is the satisfaction of the need for physical intimacy and human touch, the advancement of trust and exposure to a level of vulnerability that may be necessary for healing.
On the other, with vulnerability comes risk. Risk of emotional involvement, risks of one person wanting to continue when the other person doesn't, risk of hurt feelings.
