I'd lose the "Unsure of online dating" stuff. You're giving it a go, so just present who YOU are. Your profile doesn't need to bring in your feelings about what you are doing at this stage. Leave that for some other time and place (not for your profile)

Remember that "online dating" is just a meeting point, not an actuality. We only "date" in real terms, not through a computer screen. But we can make great contacts and even some friends this way.

Cheers.
