I'm wondering because I would love to be that fun, outgoing guy that can talk and keep people entertained; but I have only managed to do that in few situations. I feel like my monotone voice holds me back entirely, in 1on1 and group conversation. I don't know if I bore girls to death when we converse and how to sound more fun and entertaining.

Is voice therapy an option? I wouldn't know the first thing to improving my voice projection.
