I started drinking?

Not long ago i started drinking, maybe i went three or four times. And not in any of them i felt the slightest warmth, or tipsiness they talk about. First time i just had a glass of wine so it makes sense. Second time i had a beer, which also makes sense. Third time i had a piña colada with one shot of rum and i felt nothing and now where it starts to not make any sense. Im a male, 54kgs. Im thinking next time to get a piña colada with double shots. Or maybe just get two regular shots of whiskey, vodka or rum. What do y’all think?
