So this is just a thought provoking and interested in opinions thread.
The other day I was talking to a friend who was telling me about a friend of hers thats just found out her husband has been having an affair. It transpires that this couple had only had sex a handful of times in the last 5 years and nothing for the last two years, she didn't want to and had basically made him celibate. My response was along the lines of no excuse for an affair, leave if you're unhappy, but what did she expect.
Anyway this got me thinking that the biggest reason for any (otherwise normal) LTR/marriage break up and/or affair is a mis matched sex drive between the couple. Whether both of you are at it like rabbits or both are rarely interested in more than a cuddle, surely being on the same page as far as sex goes is the key to couples staying together for many years.
Just interested to hear others thoughts on this one
