The 'X-Men' comics are known for excessively steamy hook-ups; pretty much every mutant has gotten down with every other mutant. They're very incestuous like that.

And in the new film, 'X-Men: First Class,' those frisky mutants are no different. There are flirtations and smooches between quite a few different pairings -- most notably a near-miss between blue teens Mystique (Jennifer Lawrence) and Beast (Nicholas Hoult).

The prior movies in the franchise ('X2,''Wolverine,''X-Men: The Last Stand') have also had some notable sexy scenes. For mutants, they sure have basic human hormones.

We've listed some of our top 'X-Men' movie hook-ups, romances and flirting below. (More like the "seX-Men," am I right? Ergh. Never mind.)
