Alcoholism: can the child of an alcoholic dad (not mom) drink?

Im a 15 year old male, (5' 6" and 130lbs)...my father has been an alcoholic since he was 20 yrs old, he is now 45, and he has been sober for about a year...he was an alcoholic when I was born, and all through my childhood...many people tell me that "I should never ever drink" because alcoholism is "in my genetics", I do not have the disposition of an alcoholic. I know this because about a week ago, I drank with a buncha friends, and I knew when to stop, and I haven't had any craving at all. I didn't binge drink, (I had a bit more than 10 shots over 3 hours). And aparently I have a high tolerance becuz I didn't puke or fall on my face, and my friend (who is 200lbs) had the same amount, maybe a little more ended up puking lol...so I didn't "not know when to stop", cuz I cud have drank A LOT more, cuz we had a whole other bottle but I turned it down...I personally think that I have a **** load of will power, because I have turned down drinking and other "drugs" numerous times, the only reason I drank this time is because I was with really good friends (a group of like 9 othr ppl, and I've known them since I was like 2). With all this info, can whoever answers this give me an honest opinion of whether or not I can drink once in a while, or whether or not I should never drink...plz no bs answers, and I really don't wanna hear about "morals", or legality...to anyone who answers Thank in Advance!!!
