How can I stop being a bundle of nerves around guys?

Hey!

My question is as follows: I get really nervous, stiff, and tense around guys…even ones i dont have an interest in! I become extremely quiet and retreat into myself. I'm kinda getting sick of thr exhaustion and pressure lol! Plus, my older brother usually has friends over and im so anxious to be liked by them but i end up just being superd quiet and stiff. Help!
