Sexy "th"

[Arnold Zwicky]

duane campbell asks about actually (protruding) interdental
theta in english.  somewhere peter ladefoged suggests that this
is a specifically american variant, and he has a photo of a
man with this sort of production.  he'd be the person to ask,
certainly.

i myself have this variant, but i suppose i fall under the gay
exemption clause.  but my guess is it's not sex-linked.
