Should I get breast implants?

Im 22 going on 23 and I'm about 5'6 and weight about 210.. so I'm a bigger girl. Currently I have a DD cup, however I am working out and they seem to be... less full. I want to get implants for two reasons. A.) they seem less full and less attractive and plump. and B.) My husband loves large breasts and fully supports my decision to make them bigger. Should I though? I want to feel sexy and attractive, especially since my DDs dont look as good as a 150lb chick with DDs. What do you think?
