I drank a lot of alcohol and felt literally nothing??

Just turned 21, very little experience drinking, but I’ve gotten tipsy multiple times. I had 5 drinks, a shot, then a big glass of wine during dinner right after, all in the span of about 4 hours, the most I felt was a little warm but it wore off after 10 minutes. The night before, 2 drinks got me woozy so I stopped there, last night though I wanted to get tipsy again so I just kept drinking thinking it would eventually come but it didn’t. The friends I was with drank less than me but were clearly intoxicated. Is there an explanation for this ??
