Take the seats in the very back row, and make sure you've got space around you. I prefer the back corner of the theatre with my boyfriend when we go to movies.
That way we can kiss silently and makeout a little, if it's not super busy! It never fails to excite me!
Just be respectful and make sure you only do what you're comfortable with.

If you sit in the back where no one sees you, then kiss away.
