8.5 years
We were married 1977 and sex was several times a week. After 4 children over 8 year time period, she was not as interested as before children (understandable). Went to weekly and then monthly, then three or four times a year. After my vasectomy, 1990, every stopped. We separated 2005, divorced 2006 and I have been single since then. So all up nothing sexual, with any ladies, for the last 32 years.
