Animal Erotica (Intentional and Otherwise) in Comics
Comic Books:
Archie Comic's "Teenage Mutant Ninja Turtles"
An anonymous reader reports: "Comic books 28 through 70 feature a rather cute vixen (who happens to be my fave character) of the name "Ninjara," real name revealed to be "Umeko" in issue #46. She got shot and left in issue #70, which I think is the reason that the comic book ceased to exist after another five or so issues. =( She added a classiness to the comic book, and, if I recall--it's been awhile since I've read through my collection of this series--some of the scenes are unusually sexy, and occasionally slightly suggestive. She first appeared in issue #28, and appeared almost constantly through to issue #70. She and Raphael have a special issue (one of those 48 pagers). Drawing in that special's kinda lame and there's nothing suggestive, but it's still pretty cool."
Sonic the Hedgehog (all issues so far)
An anonymous reader reports: "Nothing suggestive, but Sally's pretty cute, especially in the later issues."
Serial Comic Strips:
The Far Side (Gary Larson, syndicated):
In one cartoon where two sharks are resting on their backs in the sea, one of them is clearly and deliberately drawn with claspers (the male external sexual organs).
