I really don't see what you were hoping to accomplish with your OP and what kind of feedback you were expecting to get.
If you can have a couple of glasses of wine here and there, then good for you and by all means enjoy it: that's what normal people do.
No need to obsess about the whys, how much and how and no need to broadcast it to the world.
Just have a drink here and there and live your life.
If at some point you realize you can't handle it then you already have an account on SR and you will find support if you decide to abstain from alcohol and other mind altering substances.
You are an adult: it's your life, your choices and your consequences. No one can force you to drink and no one can stop you from drinking.
Good luck to you on whatever path you chose.
