AnyFucker- I could have bet a £million that you would respond exactly as you have!
If you re-read my post, you will see that I talk about scale . I try to show that tucking into too much food or too much booze- when your brain is saying it is unhealthy, but you cannot control your desire for that mince pie or wine- is an example of how you, or anyone, is not in full control of their behaviour. And it does have consequences.
For example, 25% of the population is obese, diabetes is escalating, the cost to families in terms of ill health ( cancer and CHD all linked to being overweight) is enormous- and all because people cannot control what they put into their mouths. Ok, it's not sexual infidelity but it is behaviour that results from a lack of self control.
Sexual appetite, desiring a thrill from using prostitutes, whatever, is another form of appetite that some people cannot resist.
No one is saying they are identical but I don't believe you cannot see that they are both examples of someone giving in to behaviour that is destructive?
I take issue with your addictive and compulsive behaviour does not exist- or as someone said they "don't do it".
That's a very flippant and rather shallow way of dismissing what is in fact very common human behaviour.
So far, the OP's DH has got a thrill out of his behaviour . He has had no consequences to deal with. Just like someone who gorges on pies until they have a heart attack, or a smoker who gets lung cancer.
Your use of emotive language such as "puts his dick into prostitutes" is not very helpful. It's terribly Daily Mail hang 'em and flog 'em brigade, whereas stepping back and encouraging some kind of understanding _ though not necessarily continuation of the marriage- is what is needed.
