How do you assert dominance with other men?

TL;DR: Help me stop being perceived as beta with men

I recently found TRP and have been trying to apply principles into my life with some success. My beta self when it comes to women is changing and becoming more alpha, but with groups of men, I find myself to be in a beta role. The other men in the group tend to pay less attention to what I say and playful teasing tends to be focused on me and less on the men in the group that I feel like are perceived as alpha by the other men.

I don't know what I'm doing that makes me a beta in the eyes of other men. The only way I can perceive to make them respect me more would be to become more physical, but is that not losing frame?
