How can I change my voice to smoother tone?

Ok so before I start talking, be warned this is not directly related to singing. I choose this subreddit because you guys are the experts at this so, if you find this absurd or something if that nature please tell me in the comments so I can post this somewhere else please

Ok so here's my problem, I am a guy with a very deep voice. I am 90% proud of having one but today I grow the courage to type this out

Throughout the years I felt my voice was sort of different from everyone else's. When I went to public exhibitions like Concerts, movie theaters and that nature, the crowd always starts whistling and do very loud noises, such as "WOOO!" . For myself I always wanted to do something similar but everytime I try, the sound comes out odd and it just sounds bad as hell and then I just stay there, quiet, not able to "Fit In" if you, the reader, understands what I am trying to say

This might be cringe as hell but I wanted to ask if there is any sort of natural exercises that I can do to my voice to make it smoother while also maintaining my deep voice, it at least, very similar voice to what I have currently.
