Most men don't want to fvck their daughters, so I fail to see the relevance...
So, lets get this straight.... You already admitted that your 18 year old self was not rational, and made very stupid mistakes, like most 18 year olds... You would rather your daughter be with an 18 year old who hasn't learned life lessons yet, that can talk her into stupid situations? Like drinking and driving, or drug abuse, where a 30 year old has been there and done that, and isn't interested in making stupid life decisions... Good parenting.....
