Does dating cause you anxiety? If so, how do I handle it better?

When I first meet a guy I'm okay, it's not until we get intimate that I freak out and take a step back and sometimes I tell the guy "let's just be friends" despite liking him and wanting to "date" I do this because I don't want to be friends with benefits and sex makes me vulnerable and I don't like that. I'm working on my intamacy issues but sometimes I know I mess it up and let my emotions get the best of me. I desperately want to be chill and take it day by day, yet I feel uncomfortable in the in-between stages of not knowing.
