I will possibly come as a big surprise to many dare I say it, younger people and perhaps older ones too but I have never had another partner but mrs comm...she was 15 and I was 16 when we first met and I have never had any body else before or since..and to my knowledge, and I have no reason to think otherwise, has she. That was 62 years ago .
We both have lots of sex drive and have three great kids....tailed off some in later years but happy with that..
I can't say I have ever been tempted to "stray" but got a lot of stick at times at work for not being "one of the lads" whatever that might be....
Doesn't make me a saint and happy for others to do their own thing but must say a couple of our lifelong friends are now with different partners and have had some unhappy times ....I thank my lucky stars we came through our problems such as they were....
Just the ramblings of an old guy but just thought I'd put my POV down..:-)
