How to not get intimidated at the gym?

I’m trying to lose weight so I started going to the gym. I like doing the cardio machines but sometimes I also want to try the other machines. The thing is that I’m a complete newbie so I’m a bit nervous about trying the other machines, especially if it’s mainly guys in that area. Like I know I shouldn’t feel nervous, but I’m always worried I’ll get judged. And some of the machines seem too big for me, so in those situations, I feel kind of embarrassed that I have to leave the machine because it’s too big. For example, last time, I tried the abdominal crunch machine and I was able to adjust everything, but even then, my arm couldn’t rest on the base thing since it was too big for me. Like I just feel nervous that I won’t be able to use the machines correctly and then people will judge.
