What a fantastic idea, just another forum for the mods to have to sift through...because we're not busy enough already!
I see your point, and I do think since we have ladies forum, we could also have mens forum, however I don't agree with encouraging it to be a forum where the aformentioned topics of masturbation, porn, lust etc be continually discussed.
The ladies forum is purely to discuss 'girl issues' that we might not want to talk about in front of males, and to get advice and counsel from other Godly women who have had similar experiences. The idea is to be a place to receive encouragement etc. Now, I know the same could be said for the mens forums, but regarding those topics mentioned, I haven't ever seen a thread on those issues that hasn't had to be deleted/edited etc.
I can just see this being a whole pile of extra work, however I'm not against the idea.
