Now would be a good time to discuss gender roles with your plant and explain sometimes feelings inside may not match bodily organs on the outside. I would not immediately assume that your plant identifies as male even though it has male reproductive organs. It's best if you and your plant treat it's gender as a journey of self discovery. I would recommend against exposing your plant to gender centric toys or clothing as this may tend to cause confusion or improperly pressure the plant into making a decision before it has attained emotional maturity and can make that choice on it's own.
Regardless of the choice of gender your plant makes you should be supportive.
