Uncut/intact boyfriend?

Firstly.. Tomorrow is our 6 month mark. We are both virgins and we will NOT be participating in any sexual conduct until we are MARRIED. I just turned 18 and he is 20.. We will likely be getting married early next year. I was just wondering if there is anything I need to know since he is uncut. BJs, sex itself.. What do I need to know and expect? Thanks for your time you guys. And feel free to email answers. You can be as graphic as you want, hehe.
