For the OP, I do sing in public. I was in choir and swing choir in high school, then I sang in choir in college my last two years. And I sing in church whenever I go, which is not very often now days. And there is the “Once More With Feeling” sing alongs at various cons that is a blast to join. Although Sweets’ part in “Through the Fire” can be a bear. I love to sing, and spent the 2 weeks I just spent driving around the western US singing with my CDs, very loudy, and not necessarily very well.
I sing bass, my comfort range is in the area that Trace Adkins and Josh Turner get down to on some of their songs. Although Josh actually sings more of his songs in that range. This can make singing along with Jimmy Buffet or Gloria Estefan a bit of a challenge. My complete lack of spanish can also make Gloria a challenge, but it is still fun.
My speaking voice is higher then my normal singing voice. I have quite a few people not believe me when I said I sang bass because of it. I knew one guy in college that had a bass speaking voice. Very deep, near the bottom of my range. The choir director was very excited to hear it, until he found out that the guy’s entire range was less then an octave. I could actually sing deeper then he could, which was pretty sad.
