I just wanted to heartily "Second!" Thinker's post.
Also ... maybe I'm offbase but I sense just a hint of this in some of your wording ... I think it's a great mistake to approach any discussion of your needs in an apologetic or defensive fashion where you wind up rationalizing your position. I'm not even going to weigh in with, "You're so reasonable to want a normal physically-intimate marriage", etc. You don't need me telling you. The important question is, do YOU believe you are reasonable to crave and ask for that? Do you think YOU deserve it, as much as anyone else? If you can't answer, resoundingly, "YES!!" to both those questions, you're not ready to have this talk. Women -- well, anyone, really -- can sense supplication.
