It is fine to listen to and a lot of presenters make a voice like that work well. Don’t worry about it.

If you make a career - or significant hobby - of presenting, do practice getting comfortable with your own voice as much as you can. When you can listen objectively to the sound of your voice, you can do small improvements on your natural voice to make sure you’re always clear, have a good tempo, or give it a tiny bit of character with intonations etc.
