Pru,

My spouse and I are good friends with another couple. As it happens, I work with her husband and she works for mine. Recently, though, the husband has become increasingly "friendly" toward me. One time, in a greeting, he waited until I turned my face and kissed me on the lips. Soon after that, they "dropped in" while we were watching a movie, and I was in my pajamas! I went to lie down on the sofa because my back was killing me, and he came in and said he would rub my shoulders. Well, his hands went under my shirt, and I was absolutely horrified! I tried telling my husband, but he thinks I am being silly. On top of that, the wife joked that someone at work thought the four of us were "swingers."

Is it my imagination, or am I right to be uncomfortable? He is touchy with a lot of people, but I am getting the idea that with me, he is testing the waters. And her comment about "swingers" made me wonder even more. I am not sure what to do. When I recently had surgery, he came to the hospital and spent four hours there ... I could not get him to leave! How do I say something, because what if I am wrong and he is "innocent"? Do I just let it alone until something bigger happens? HELP!

Dear Con,

He slipped his hand under your pajamas, his wife is "joking" about a four-way, you couldn't get him out of your hospital room, and you think maybe this is all innocent? Wake up, honey. Your friends are on a campaign to change partners and dance. When you ask if you should wait "until something bigger happens," all Prudie can think of is that this couple might show up at your house naked under their raincoats. Insist that your husband take you seriously in your concerns and make it as plain as is necessary to this man that you and your husband would reject any suggestion of sexual games. You are, indeed, right to be uncomfortable, you are not "silly," and your husband is dense.

—Prudie, indignantly

Dear Prudie,

Here's my problem. I met my husband four years ago, and I got pregnant before we got married. We decided to tell his parents and his two sisters. His mom was really happy, his younger sister was happy, but the older one was not. That sister and her hubby accused me of doing this on purpose to them (!) since they were married first and were trying to have a child.
