I agree with the general idea here but I would to take the idea one stage further. I don’t think porn is the only culprit. Our sexual fantasies and sexual behaviour may have just the same effect.
What we are talking about here is simply “habituation”, which is basically a term to describe the reduction in our psychological response when repeatedly subjected to a stimulus. Or in other words we are bored with it and it does nothing for us any more. We then require a more extreme stimulus to get excited.
This happens to all areas of our life, but sticking to the sexual arena this can also happen simply through sexual fantasies and I am convinced it’s happened to me.
4 years ago I had a strong healthy (some might say unhealthy ! ), Sex drive. I then met this girl, who managed to bring to my attention my dick size inadequacies. This lead to me having cuckold type fantasies about her. I got her to invent and tell me stories about having sex with men in front of me while she gave me a handjob. When we split up last year, I continued having the same fantasies while masterbating. I became very aroused by this but I started to notice that more ordinary sexual thoughts about other women did nothing for me. Eventually I got into another relationship with an attractive asian girl, but I was unable to get it up without cialis. 3 weeks into the relationship I tried going drug free, but I had virtually no interest and couldn’t get it up. Today is 5 months later and things have improved a little but I have nowhere the same drive I did 4 years ago. This could of course also be related to the size issue.
Another example may be prostitution. A few years back I developed a fascination for hookers and the thrill of having sex with a complete stranger. Too much of that and it could have the same effect.
I find it hard to believe that we can ever completely turn back the clock but I do hope that time can at least partly heal it.
