Confidence

I really want to hook up with this guy that I work with. I’m not worried about work but about my body confidence. I think I’m too big for him. I’m a US 14 and he’s an athletic guy. There is some sexual tension there that id like to explore but I’m really afraid that he’ll judge me and stuff because he’s got a good body and I don’t. I’m really stuck on what to do and how to feel more confident. Should I not pursue it because I’m scared? Also I’m a virgin 😢
