I have written about my experiences before. Our first time swinging we were in different rooms. We met a couple on a cruise and we swapped spouses. I went to their cabin, my husband stayed in our cabin with the wife. That night was fabulous. It was the first time with someone other than my husband since we got married. I can say we made love. I know have taken exception to that comment. We did make love with kissing, touching and sex. It's not that I did anything new or much different than I do with my husband, it was different because he was different. Looking back, and memories do change, I was totally comfortable kissing and having sex with this new friend. I didn't think about my husband or what he might be doing in our cabin. It was much different when we had sex with them in the same room. My new partner changed. In front of my husband and his wife we had sex. It felt detached and more like putting on a show. The romantic oral from the night before was replaced with him having sex with my mouth. When he entered me the long sensual strokes were gone. I also saw my husband watching us as he was getting a blow job. It just wasn't the same.
Even though we have been in same room situations since and I have become more comfortable with it, I still prefer different rooms.
