Short answer: check the rate, say what you'd like politely before you start, and respect any boundaries the performer sets. You can end the show at any time.
Before you start
- Check the per-minute rate and your balance.
- Chat in free mode first to get a feel for her style.
During the show
Be clear and friendly about what you'd enjoy. Performers appreciate viewers who communicate, and they'll tell you what they do and don't offer.
Boundaries
Every performer decides what happens in her show. A "no" is final; pushing past it ends shows quickly and gets accounts banned.
