Frisky, if you give me a clearer picture of the kinds of names you're looking for both mainstream and adult and what you can spend, I can check with contacts I have and/or domains I have (my premium domain plate is dipping lately though so it'd likely be contacts I have w/ domains). Shoot me an email.
Specifically some of the adult ones I was brokering a while back here were Erotica.com, Porn.tv, Porno.tv, Females.com, Semen.com, Dirty.com, etc. Some of those may still be available depending on what you're looking to spend.
