Pretty simple guys and gals. Pick three x-men (or mutants at large - no non-mutants thanks) One to Shoot. One to Shag. And One to Marry.
I'll go first
Shoot: Wolverine (coz i hate him)
Shag: Hellion (he's becoming the sexiest X-Man these days - even without hands)
Marry: Gambit (sexiest of all, charming, and you'd never get bored with Remy)
