No Mike, my views are not based on the couples I have known, as i said they were all rather old and I am sure their interest in sex would have waned.

Sorry but I think you are wrong about the figures, which stae catagorically that MSM figures are much higher that hetero, even among "singles"; tho it would appear that you validate my point about the family structure having a bearing on sexual behaviour.

Unless of course, you think the word MARRIAGE has magic properties :0)

There is nothing to stop young people from committing to one another without using "the word"...and many do.
