Gonna try alcohol (wine) for the first time soon. I have a few questions.

Helloooo, so I have never had not even a drop of alcohol in my entire life, I’m 20 by the way (the legal drinking age where I live is 18). I only want to try wine this time because of personal reasons/symbolism, but I don’t know what to expect. I plan on maybe getting slightly tipsy, but I really don’t want to overdo it. How much should I drink if it’s my first time trying alcohol ever? I weigh 135lbs and am 5’7, I have a pretty thin frame and am a girl, if this information helps at all. How do I know I’m tipsy? How long does it take for the alcohol effects to kick in? Will I get a hangover from getting tipsy if it’s my first time trying alcohol? I know these might be dumb questions, but I really don’t want to ask anybody from my personal life because I don’t plan on continuing to consume alcohol, and I wouldn’t want anybody in my personal life to see this as an opportunity to offer me drinks. Any extra info would be really appreciated, I really don’t know what to expect in terms of how I will feel.
