I do like having female characters around! They might not be the focus of BL but I think the genre features neat depictions of platonic male/female friendship that's harder to find elsewhere
Though sometimes I think I'd probably take an antagonistic female character who's offered internality...
I do them all! Though there have been exceptions (Teikoku Sensenki that I've been too tired to return to.) If there's no proper story order, I save the characters I'm most interested in for the last. I also try to do the bad endings first
