Glad to hear some input on the issue. Its an interesting issue. Another thing thats odd is unless you specifically buy bi porn, they guys won't hardly look at eachother in any porn but women even if they aren't having sex will still kiss or something. In porn or even in "real life" if 2 men and 2 women are having a 4some why the boundary? Just let it go and see what happens. Sex can be fun, why limit!
