Sorry for starting late on this thread. I just want to share the following:
In 28 years of marriage, I never had a problem getting it up with my wife; even when we had play times in which I DID have the problem with Mrs. Playmate. I did have trouble with women whom I felt didn't want to be there. In both cases, we chose to not play with the couple again.
I also never had trouble with our long-term Mrs. Playmates. I got to know them well, although they were not poly situations. I think Julie has hit on something. You may need to spend more time getting to know your playmates.
I don't have to love a woman to fuck her, but I do need to like her and I do need to know she wants to be with me.
Especially on a first-swap, I liked to start with a massage... a nice slow one in which a lot of conversation took place. While rubbing her back and dropping an occasional kiss onto the back of her neck, I learned a lot about her by asking questions that can't be answered by "yes" or "no."
"Tell me about your home town."
"What attracts you most about swinging?"
"What does your husband do sexually that you really, really, like?"
"What's your favorite sexual fantasy?" (Laura would have told you that hers was to have three men: One vacuuming, one dusting, and one cooking.)
By the time I had her talking, we were both relaxed.
Also, there is an unconcious ritual we Americans are conditioned to go through before mating, according to Laura, who had degrees in both Psychology and Communication. She had made a study of Body Language, in particular. If I remember correctly the specific steps were:
1. Friendly conversation.
2. Light touching of the fingertips
3. Clasped hands
4. Hands clasped with fingers interlaced
5. Glances at lips
6. THE KISS!
Laura's theory was that we Americans are uneasy about a sexual relationship that doesn't proceed in this way. "Woe to the person who attempts a kiss before the fingers have been interlaced!" she once told me. "It throws the whole process off balance so that it seems wrong to us."
It's obvious the problem is not physical. Be patient, explore, and you'll find the reason for your discomfort. Keep us posted!
