I think at 29 you are old enough to understand what you're doing. You are old enough to have had dating experience to the point that you aren't in danger of being taken advantage of, no more so than if you were dating someone closer to your age.

Because that's the problem with age gaps where one party is in their late teens or early twenties, even if the older party doesn't intend to, there will be a power imbalance by simple virtue of a massive gap in life experience, dating experience, and (perceived) maturity.
