I don't think it is any of the lostie guys based on this info which is just from memory so please correct me if I screwed something up.

Charlie -- likes claire, hit on shannon, FB girlfriend
Jack -- married Sarah, likes Kate, had asian girl lover
Sawyer -- sex w/Kate, sex w/Ana, sex w/Cassidy, sex w/Mary Jo
Benard -- married to Rose
Locke -- relationship Helen, paralysed last 4 years
Sayid -- loves Nadia, sex w/shannon
Boone -- sex w/shannon
Jin -- married to Sun
Michael -- fathered a child w/Susan
Desmond -- in love w/ Penelope
Hurley -- liked record shop girl, starting relationship w/Libby
Paulo -- in relationship w/Nikki
Eko -- no FB showing relationship with men or women

The girls all have simular reasons and are all mentioned above.

so if the is any gay character I would say it was in the others camp.

Everyone thinks it's Tom. Makes sense to me. None of the others stand out for any particular reason.
