So I just posted an ad as a male escort on (my city) backpages. I need a little advice

Hey there! Im a genderfluid gay male who has recently posted ads as an excort in the local transexual and male escorts pages. I just had a few questions. A.) How do I avoid getting undercover cops? B.) Is it acceptable to only offer oral services and refuse other ones or will this make me lose clients?

Im hoping to make some decent money at this. Im thinking ill charge thirty dollars for strictly a blowjob and otherwise charge 50 bucks an hour for regular making out/sexual contact. Im also considering offering dominatrix services but im not sure how to charge with regards to that.
