I have a hard time coping with this new found masculine and domineering attitude I have lately

I know it can sound arrogant but I find that I feel like I must be very careful around people in order not to appear too dominant or scary etc.

I don't know if this makes sense. All my life I've been sort of wimpy and I wanted to be more confident etc. but now I it seems I'm overconfident to the point I can come off as agressive.
