Is the first person “私 Watashi” weird!?

There’s a lot of Japanese learner who use “Watashi” as a first person.

but actually it’s unnatural.(it depends on the time, situation and gender though)

To be used by woman is natural but to be used by man is kinda unnatural.

It’s natural for man to use “Watashi” in a business situation such as an interview, presentation and so on.

What should I use!?

It depends on your personality and gender. (kind, strong, diligent, etc)

A lot of first person exists in Japanese
