My wife and I are new to swinging. Actually we have not done full swinging yet, just her hooking-up with another man. She and I do not kiss during sex, but she and her bf do. Alot. My question is - is this something I should be concerned about? Are they being too intimate and are there any boundaries that we should set? It bothers me that we dont kiss and they do. Their arrangement is "just sex" so do they really need the intimate kissing that we don't have? Am I reading too much into this? I feel secure in our marriage, but need advice about what is happening. I enjoy our arrangement and do not want it to end, but also do not want to have to worry either.
