I don't really get the jealousy thing... I mean I understand feeling like it makes harder to slash them (depending on how attached you are to canon.) But actual jealousy? Seems strange to me. (But then I'd be okay with my boyfriend sleeping with other people too, so maybe I just don't have that gene.)

Also the girlfriends add to the pool of hot girls that can be written about, which for me is a good thing. *g*
