As a recent newbie myself, I was very nervous communicating too much information for legal reasons. My takeaway is yes, be mindful of the language you use regarding compensation, but be specific about what type of experience you’re looking for. I was vague in language about “starting slow since I don’t get to play often” etc for my first meetup, and the encounter started off much more aggressive than I was expecting. (At the time, I assumed “boyfriend experience” meant no sex — now I understand BFE is a good shorthand for the kind of sex I enjoy.) You don’t have to provide a checklist or itinerary for the encounter, but make it really clear what activities you like and would enjoy if they end up happening.
Speak up and communicate during the encounter. During that first time experience, once I finally said it was not going like I hoped, the provider instantly changed his approach and I ended up having a really great time. (He also introduced me to this site as an indispensable tool for this hobby!)
