Is taking a sip of wine bad health-wise?

I am nearly 14 and ever since i was 6 my parents would give me a tiny winy sip of wine once a year, I am against disorderly drunk behaviour and I'm a good kid but I really really love the taste of wine and champagne! I do not wish to get drunk and that won't ever change, EVER! I sometimes just sneak half a cup of red wine occasionally, I've done it 3 times. I really love the taste of it in moderation. I hate cigarettes, drugs and I've never done any of those things nor have I ever gotten drunk. But does this wine thing, is it going to make me get heart disease when I'm older or slow me down? I want to stress the point that I am NOT looking to get drunk but half a cup of red wine or something, is it safe? I am strong against teenage drinking and binge drinking etc but the more I look at the wine the more i want it more often. My parents aren't regular drinkers and have 1 gl a week and don't have it showing. They have a few bottles in the pantry, I feel guilty when i sneak half a cup of it? :(
