First time drinker

I’ve never drank, or had a sip of anything. It just never seemed to interest me. I’m bored and have some free time tonight so I figured i may as well try something. What should I go with? The only things I can think of are mixing whiskey with club soda or going out and getting one of those hard seltzers i always see people with. I don’t want to blackout, but I do want to get drunk. I’m around 140lbs. Any suggestions?
