Y'know, I dunno if you remember, but there's an entire thread dedicated to that shit over at aLp, which is hilarious.

Rephrased: There is porn of this somewhere. If you know what's good for you, don't look it up. If there isn't, then there will be. I myself have probably been Rule 34'd or something, so I know there's porn of me (child porn of me in the tub with a Space Godzilla figure no less, taken by my aunt or something who didn't know a cherished memory could double as sickfuck eye candy when on the internet).

Anyway, I'd link to TvTropes, but I don't want to suck any of you into this further than you have to. Not that you'll actually stay on the article about porn anyway, you'll probably get distracted by some other page as soon as you go, "Wait, what does that mean?"

...er, back to topic, I guess?

to be honest everybody has there own ideas if there are are male and female ones. im not sure any more?

It doesn't really matter. It's never explicitly stated in the movies whether the individual xenos are male or female, so it's up to the viewer to use their imagination.

I actually prefer not knowing everything about them.

indeed adds that sense of mystery

id prefer it to be a mystery

if you knew what gender they were it would be pretty lame

In order for foreigners who do not actually like, but only a monstrous thing to kill a large dog feces meaning, in their underwear, each time you stand stupid fans...

I'm sure that may have made sense before google translate went through it.
