You back away from the man and say, "Uh... no thanks."
You then run outside to see the entire island where it's nice and sunny and there seems to be no cloud in sight. You decide to wonder off to the beach for a look at the view. You don't know how you got here and quite at the moment don't care. All you care is what you wanna do for fun on this strange packed island. The beaches are nice and smooth, the people are happy, and the clear water is glistening.
You then notice that there's three small gates to the beach and one of each says one thing only:
'Gays only'
'Bi's only'
'Hetero's only'
