Have any of you successfully cruised before?

I’m in NYC, so basically the kingdom of cruising and sex parties. I’ve been on a fitness journey and am starting to feel more confident in my body, and want to try cruising. The problem is…I’m absolutely terrified. I am 5’9 and 100% cis passing, so I don’t think most guys would assume or guess that I’m trans if they were perusing me. So I think…how am I supposed to tell a guy? When? What happens if he rejects me? I just cringe thinking about it. Would love some insight from guys who have more experience with this
