What's the longest amount of time you've had sex? My husband and had been friends for several years, secretly lusting for one another without knowing that we both felt the same way. After we finally got together as a couple we had hot sex every day for 3 months. Our longest nite of hot sex lasted for 5 non stop hours. I was so sore the next day I could hardly walk but, with each step and nagging pain I had to smile remembering the hot passionate nite before. That was several years ago and nothing has come close.We still lust for one another but, I sometimes miss how we couldn't get enough of in the beginning.
