Sure.
Amber Lee Connors and Natalie Hoover are in Kanojo x Kanojo x Kanojo.
Amber Lee Connors has been in a few others
Sarah Wiedenheft, Brittany Lauda, and Amber Lee Connors were in Huniepop (while not an actual hentai, there's porno moans)
I forgot the name of it but Matt Shipman and Brittany Lauda were in a show. Forgot the name. Something Dere, episode 2. Amusing since they're married IRL. Also because they play Hiro and Ichigo in Darling in the Franxx.
As for Stephanie Sheh, I think it was at a time when a voice job was a voice job. She hasn't done anything hentai related since.
And yeah, I find the whole english VA thing to be more amusing than titillating.
