I think the post was thrown under friendslock? That might be why you can't find it. I'm pretty sure you could just Google it and find it somewhere else, though.
Also -- you are right, the X-Men all really went for it there. Which makes sense. I guess. Because Iceman also did that one group X-Orgy comic. (That one burned itself into my memory, see.)
Speaking of Northstar, no, it's clever commentary on how Jean-Paul's treated in canon. Even in a gay porn comic, the gay X-man doesn't get any!
