Someone else's bedroom? I do best on a bed. Which may be a reflection of my age. Certainly when I was young I was less particular - in the back yard, in the open , being held up outside against the back wall of a nightclub, on a bathroom floor at a party etc. - though I preferred a bed. One man - oh should mention we used to take separate vacations with another couple and he was a client of my husband - liked being with me on the deck of his boat where other people might see us which I went along with but never much cared for. When we went below in the afternoon that was for me. I have engaged in quite a bit of motel sex which is very comfortable and relatively anonymous. As far as our home is concerned in more amorous days we used to make love on our living room sofa or he would start with me against the dining room wall and then carry me upstairs to continue. Should mention that we have three bedrooms and for a long time I would only entertain gentleman callers in the other two while keeping our bedroom - which actually was a large utility closet with no windows - just for the two of us. But now that he is only occasionally interested in being with me that is more violated though I would never be with anyone there when my husband is at home or if he will be coming home.
