Hey...congratulations.. I'm getting married on the 11th !
Be tender, gentle and loving with her.. lots of kissing on the lips (its romantic), and then kiss her all over, caress her gently, and pay attention to her responses, to see what she likes and what feels good for her. Also, most women like the missionary position, they like to feel the weight of their man's body on top of them and look up and see the love on their man's face. There's plently of time for all the kinky fun stuff later. But first time.. make LOVE to her.. not just sex.
