im also from sweden and i dont mind if i would see gay couples kissing.
i dont think u have to be gay to like yaoi, most yaoi readers are girls even in japan. i dont like hentai becouse i think its written in a guys way on seeing sex.
yaoi have also mutch more story in it.. and gravitation isnt any yaoi its shounen ai, but still is my favorite shounen ai ^^.
i watch shojo ai too.
i love everything with romance in it.
