Make sure that things which could interfere with enjoyment of sex are out of the way, in particular if you are using contraceptives make sure that you have them with you and have sufficient supply, possibly take lubricant with you to enhance sensations and prevent discomfort. Even though it is your honeymoon, this doesn't mean you have to pressure yourselves to be sex monsters - enjoy yourselves but don't gorge if you don't feel like it! Relax and don't put yourself under any pressure - this is more likely to result in disappointment. The wedding can be stressful, try to relax and enjoy that too, the last thing you want is to be bickering with your new husband - this really doesn't bode well for sex...so try to get things in perspective, this is just the beginning of hopefully the rest of your lives together, so relax and enjoy as you both see fit.
