aishuu did a meta on genderswitch over at risingtides I think? There's another perspective to note.

I think in essence the same applies to what I responded to a discussion about transgender issues -- most of us are curious about what'd it be like to be the opposite gender for a day or a week or a month. A lot of people wonder how the orgasms are on the other side, if you will. That's why a lot of genderswitch goes directly to the porn because that's probably what most people WOULD be doing if they woke up male...or female.

Other than that, it's fascinating to see how your favorite pairing or character would be as heterosexual, or lesbian or gay. It can seriously change behavior and dynamic and leads to interesting what-if thoughts. How would they have reacted if this 'forbidden love' type pairing was allowed. Would all the tension be gone, or would it remain completely the same? It's stuff like that that drives people.

On my completely shallow note? I like lesbians and I think it's fun to turn my het and gay pairings into lesbians. Also, the OH GOD I HAVE BREASTS joke makes me laugh every single time
