Nip/Tuck; what was Eva's final surgery?

Last night FX showed a bunch on Nip/Tuck episodes and I watched the one where Eva first met Matt. Matt saw her naked and had sex with her so clearly she’d already had genital surgery. So what did she make Sean do?

I’m pretty sure Sean just made it more “lady-like” down below. Matt was relatively inexperienced and could not notice the difference.

Yup. Something about her vaginal canal being too shallow, IIRC. Christian noticed since he’s pretty much slept with every woman ever, but Matt didn’t realize it.
