By experiencing all emotion at an enhanced level, they'll make sure you do the same. And with psychic abilities they can operate everything at once.

Under all that armour, they're really big softies. You just need to know where to touch them.

And you think some of the other races we've discussed would?

Three fingers and know exactly what to do with them from a single touch.

Under those military fatigues, they're close enough to human to fill all the roles needed. If you're lucky they may even have some practical cybernetics to enhance the experience.

Quills and a long snout/beak provide excellent stimulation, but one needs to be careful of the teeth. Unless they know how to use them.

I'll bite: What are the other two?

When you have a memory like that, you never run out of ideas. They'll never forget a date, or the morning after.

Don't interrupt our nerdgasm. Join in if you like.

It was 6am, I fell asleep. Their mouths line up pretty well though, for all sorts of fun times. And teleportation makes them always there when you need them. RIGHT where you need them.

By the Emperor, they may be heretics who love nothing but war by day, but they're still heretics who sure love something else at night.

Promises of night of honour and conquest makes them fall right in, and a quad-jaw can work wonders in ways one wouldn't expect.

Centuries of experience and come flying at you from all directions. Everyone loves a good Goul Band.

Not only are they the future and superior in every way, they're completely sterile which solves SO many problems.

They can do aerial acrobatics, and look flaming hot doing it. And the ending is always explosive.

Spindly fingers can get up into all the tight spaces. Way up into the tight spaces. Far more savvy than normal ones too, in EVERY way.

You can go at them for ages and just when you think they're done, they rejuvenate ready to do it all again. Really puts the wood in a knot.

Which one is irrelevant. The strength, the MUSCLES; better than a bodybuilder any day.

Extendable, nimble tongue; long, smooth body and excellent agility.

It's a shame they're missing a mouth. Maybe they have some other implants they can use.

Oh hell yeah. No fancy comment for these guys, just Tali and Kal all the way.

I hope the vials don't get in the way.
