What are things that intimidate you about the opposite sex?

Straight up, the motivation for this is that I see girls clam that guys are just intimidated. I haven't experienced that except for a single occasion on some dating app a couple of years ago where she was more adventurous than I am and could prove it. We're talking reincarnated Magellan/alligator wrestler/desert trader all at once and at age 25 levels of adventurous, and it was as almost like, "all right, I really can't keep up with this girl." I think I shot my shot anyway, but that was the one time where I would be mogged and would struggle to keep pace, let alone lead. So, what intimidates you?
