Oh gawd. No. Giger is the guy who drew concept art. Ridley Scott and the directors who came after him made the Aliens as we know them, not Giger. Giger drew a lot of dicks in his time and probably claimed they were all female and that's alright, since they're his dicks. But the actual xenomorph creature wasn't created by Giger, it was only based on his artistic depiction of a thing with a dick for a head and a long penis with a skeleton at the end. Which apparently makes it female. Get your heads out of Giger's ass.
