I think you'd like Oglaf, yeah. It's super NSFW, as mentioned. Ma3, not so much sure you'd like that one.
I think comics you might like include Goblins
(Dungeons and Dragons, from the perspective of the low level monsters), Girls in Space
(I don't think I need to explain this one), and Judecaa
(I thought of it when you mentioned liking like, the horror and sexuality blend in Flipside. It's a bit weird, sort of urban fantasy thing). I also think you might really like Homestuck
. It starts out pretty slow, but it does some pretty crazy stuff, including flash animations, etc, touches a lot of genre bases.
