great! you are a lucky guy.
my gf likes porn, too. every once in a while we watch it during sex. miscellaneous porn, not only one category. sometimes it happens to be interracial but not the cuckold stuff, yet. she prefers it when there is "lots of action" going on, like in group sex or gangbang scenes; but sometimes also the "romantic" type where couples really seem to enjoy themselves - often amateur flicks.
i try to increase the number of watching Black Men on white Woman type of porn with her, along with the amateur swinger`s party stuff. she seems to enjoy this a lot!
my woman also told me she sometimes looks at "porn tubes" when alone, masturbating.
Mhe.
