Riveting discussion! Here's what I mean when I say PSE: higher-paced and more action packed than what's generally understood to be GFE. Also, deep throat, gagging, facials, and anal.
These days, I don't prefer cum in my mouth. Something I appreciate about PD is they have a "No list" where a companion could check of whichever acts they don't want to engage in. More important than lists and definitions is the understanding that consent isn't fixed and communication can help ensure everyone has an enjoyable time. Personally I'm always open to clearly communicating about the experiences I offer once screening is complete.
