Can’t Blackout

For reference I’m a 20 year old college student and drink about 3-4 times a week. I’ve never blacked out or even had memory loss. I can drink 10+ drinks/shots and will be conscious and fine the whole night. There has been two times where I have been violently hungover, and if I had to guess drank around 15-20 drinks and shots over the course of 3 hours. I remembered everything, even the name of a random girls instagram. I don’t necessarily want to blackout but it’s just surprising, does anyone relate?
