Quote From: tautologyMy boyfriend accepted a job a year ago that is many miles away with the result that we see each other only once a month or every other month for a long weekend. He has always used the internet for pornographic sexual stimulation. I do not object to this. However, since he has been gone, his use has accelerated and his usage has been increasingly demanding with the result that he needs more sexually explicit scenes to stimulate him. He can no longer attain and/or sustain an erection when he has sex with me. He does state that he does not have that problem on the internet. He does refuse to get high on the internet with me stating that it is a private experience. 
 
I now consider him to be addicted to the internet as he has to view it everyday. Can his internet addiction be the cause of his impotence with me? 
Porn can be VERY desensitizing. There was a Dr. Phil episode that discussed this.
He HAS to view it everyday??
If his use of the internet is interfering in his everday functioning and/or your relationship, he may very well be a sex addict.
You need more information. I suggest you talk to a counselor who deals with sex addiction.
