Congrats to you for waiting! My boyfriend and I are 27 and we're waiting until we get married to lose our virginity to each other too. We've been together for almost 10 years though, so we've done all the "foreplay" stuff, just not intercourse. I don't know you're situation, so I don't know how comfortable the 2 of you are with each other. With me, since my boyfriend and I have gone out for so long, I'm not nervous at all about making it a special night.
I guess what I'd say is take it slow and enjoy it. Spend plenty of time with kissing and foreplay and all that good stuff, don't just rush into it. You'll want to make sure you're good and worked up, haha. Then just go with it... it's pretty instinctive, you'll know what to do. Clearly you're old enough to know what to do. If you're waiting for religious purposes, you may have not watched porn before... but if you feel ok to do that, you could check out some amateur videos online for free, just for research. If you don't want to get pregnant yet, make sure you have birth control (the pill, condoms, spermicide, etc).
And you might be too exhausted on your wedding night to do it. Don't feel bad if that happens. You'll have spent all day getting ready, going through the ceremony, dancing at the reception, talking to all kinds of people, etc. If you drink, don't drink too much at the reception (or let HIM drink too much) because that will RUIN your night.
Just have fun and be safe! That's really all there is to it. Good luck to you both!
