Even in 2 years, when she is 16, it wouldn't be exactly socially acceptable for her to be going out with a 24 year old. Although, if she is mature enough, she could decide to bring the relationship to the next level. Just check your state laws on age of consent. But, since you are asking my opinion, I don't think it's acceptable at all. You'll be almost in your mid-20's, while she is hitting some of the peaks of her youth. She should be going out with guys closer to her age, if at all.
