Me too. I tell myself I wish I had been able to come out as a teen or in my 20's. But then I stop and think about what society was like at those times and I think maybe I waited the perfect amount of time -- to when both society and I were ready for it. Ours are the sad stories of people at the time when the culture was changing. I hope that future generations will never understand why we waited so long.
As a practical matter, having rented a few storage units in my time (for reasons unrelated to gender,) I'd have to say even six month's storage equates to a pretty penny -- I think if it came down to that choice, you're better off putting the money aside to buy a new wardrobe.
