HEY! I am not a cougar, this time! I went through a slump where I just wasn't interested in sex and then all the sudden the drive came bacK ~shrugs~ When LK was going through his worst time with PTSD he wasn't interested in sex at all and it must have been several months. It seems normal that the sex life ebbs and flows with the stresses with life. Those that are only 1x a year them & their spouse need to see the Dr. There are so many physical things it could be, a simple hormone imbalace in women is VERY common.
I have a very good friend that her & her hubby have had sex 1 in 7 years. he's an alcoholic and apparently can't. She wants him in Rehab soooo bad.
