Dear Steve and Shirley, My husband and I live in a duplex and his brother and the brother's girlfriend live next to us. I don't get along with a girlfriend, and she knows she will never be welcome in my house. My husband's brother and I are the same age. We're forty six. My husband is fifty eight and he has problems with sleep apnea, so he's been sleeping with a CPAP machine to help him sleep at night. Because of it, I don't have a lot of sex with my husband. I have it with his brother instead. He gives me all of the great sex that I want and need, and we don't even have to sneak around to do it. He comes over after my husband falls asleep, and the sounds of his sleep machine drown out any sounds we're making in the next room.........................................................
