This thread has been quite the interesting read.
Lesson learned: Whatever your feelings on one topic or another, if finding out that your partner is doing it or thinking it will cause you to fly off the handle and lose all trust in them, best to find out their position on it *before* getting involved.
If you are offended by porn, or think "it's for losers", get that out up front. If you don't, you have no one to blame but yourself. Getting on a board like this *after the fact* for some validation for your feelings only hurts things by giving you a skewed impression of what "the general world" thinks about an issue.
For the record, every guy doesn't lie about watching porn. Actually, most of the people I know would freely admit something like that. Guess we're just a bunch of loser degenerates though.
You are who you are, and want what you want in a relationship. End of story. I'm still wondering though how some of the comments about those who would want to watch porn are acceptable, when they clearly wouldn't be acceptable in speaking about other aspects of relationships...
