Speaking on behalf of all of us for whom "sexy" is no longer (or never was) an option, I say go for it. The day will come when nobody wants to see your tattoos anymore, and they'll no longer be in the same place they started out anyway. Celebrate today and enjoy what remains of your youth, lest you someday regret that you never did.
As for what your husband thinks, all you gotta do is ask him. He'll be cool with it, I'm sure, but he'll still appreciate being asked.
