You know, arj, I would lose the "it's okay sweetie.." stuff. The reason: It gives her the impression that you are expecting her to do bad at this. She will then be sure to live up to those expectations, kwim?
Instead I would soothe her with words of love...words that come from YOUR heart, not words that are ASSuming her state of mind and what you can do to FIX that. Think "I love being with you and being close to you. From the minute I laid eyes on you, there's been no other for me." Lots of endearing, soft, gentle words but nothing that treats her as if she shouldn't be enjoying this...as if it's some weird experience. How crazy, right! She's getting close to her man. There should be no "there, there" needed. Be confident and loving and she will naturally follow your lead.
I think you are on the right track with wanting to have some words ready so you don't fumble, but make sure that you don't self sabotage.
