Pre-sex disclosure is unquestionably a tricky moral issue, and not just for trans people. If I'm in an open relationship, should I have to disclose that to every one-night stand? If I'm separated but not technically divorced, should I have to disclose that, in case the person has a moral qualm about it? Honesty is always good, but some of these conversations are definitely mood-killers.

But in this particular scenario, well, it's more than just a mood-killer. I agree that realistically, the vast majority of straight males are (at least) going to be weirded out by the idea that they unknowingly slept with a post-op transsexual, and that this has to be taken into account. But while acknowledging that, there is another angle to look at the issue from, and that is the perspective of the trans person (obviously).

If you're going to say to trans people that they must warn every prospective sexual partner they might have, while that might be a view based on our perceptions as straight males of what's realistic, we do need to at least explicitly recognise that it's not without consequence for the trans person. Not just the 'trans-bashing' risk, either. It must come out as somewhat psychologically tricky - there must be self-esteem issues, for one, in essentially having to warn people about who you are all the time.

I dunno. It's a tricky one. The only thing I'm sure of is that Family Guy really isn't that funny. ;)
