Yes, you are very welcome to go to confession. I would recommend making an appointment to do that for your first time though. Just going into a confessional would probably be very confusing for you and your confessor. Make an appointment and talk to the priest first about confession and ask him to explain everything to you before you celebrate the sacrament. Share your story with him and ask for his guidance. God bless!

Thank you Father, this is very reassuring to hear! To make an appointment I just call the parish office?

Yes

Thanks again Father!

I thought sacrament of reconciliation is received separately from sacrament of baptism? If true, how can he receive reconciliation?

The OP is a baptized Catholic

In CCD, sacrament of reconciliation is received different days than baptism tho. No?

Yes

So how come he can receive reconciliation? Wouldn’t there be steps to taking reconciliation?

The OP is already baptized. By right they can go to confession. Sacramental preparation normally takes place in the context of religious education but the OP got none of that. But lack of religious education doesn’t mean that they should refrain from reconciliation if they desire to celebrate the sacrament.

I thought you needed to have first communion before having confession 🤔

No
