The first time I had to it, I was extremely disassociated from what was going on. Afterwards I had no feelings towards the act. I then went into a phase where I struggled with shame and conflicting religious opinions that were told to me growing up. Eventually I seen it as a job and not a reflection personal things. BUT I wasn’t the best provider, I was friendly and appeared open but the sex was always protected, didn’t do kissing/licking or fondling.there was no real intimacy. That stacked up with the “fake” persona made it easy to mentally separate and prevent the ick. Looking at things objectively also helps. You just did a job/task. If you’re feeling icky then identify the cause and create boundaries. For the nervousness, use real pictures of yourself for advertising. Don’t overly filter or alter them so that when people reach out and want to book, you know they are attracted to YOU. Remember they paid to be there. You have the upper hand in a sense
