I had gone through your query and like to suggest you that you should go with everything that you like because its not like that what should you do at first night.
It depends on you and your wife that what you both going to enjoy. It could be kissing licking and something else what you like.
No one could suggest you better than yourself for this issue.
Still i would like to advice to concern a good sexologist for the best advice.
Hope you will find it helpful.
