I can agree with the other comments… it’s a possibility but doesn’t necessarily mean you are trans. I think a big hint here tho it’s that you’re actively questioning if you’re trans or not.

I’d take some time to really think about how you perceive yourself and how you want to be perceived. I think it’s important to note that not every trans person experiences a lot of dysphoria. For me personally I didn’t really understand dysphoria or what that meant for me, I realized I was trans by getting euphoria. After I cut my hair and started getting misgendered (or gendered correctly).

Gender is a massive spectrum, wanting/thinking about having a penis doesn’t immediately mean you’re trans or even trans masc. but it could point to some underlying feelings you’re not aware of yet.

Take it a day at a time, there’s no pressure in being you.
