I totally agree with this.
Also, no one has mentioned it, but you should discuss with your future husband about what your expectations are for the wedding night itself. If you have the ‘traditional’ dinner + dancing reception and don’t make it to the honeymoon suite until almost midnight, after an emotional wedding day and perhaps a little bit of drinking, you both are going to be exhausted. And that first time takes TIME, as others have pointed out. If you have an early morning plane to catch, it might be best to wait to consummate…
As far as actual resources…I’m not sure I would suggest looking at them before or after the wedding. I think everyone is different, and it can ease some people’s anxiety to read a little about what to expect beforehand. If you google “The Marriage Bed” you can find a resource created by an evangelical Christian couple that actually does include a very good “what to expect” for both bride and groom. The downside here is that their site is NOT in keeping with Catholic teaching–they are totally OK with contraception and actually seem to recommend it, and are also OK with oral sex. If you
really don’t know how sex works and it’s making you anxious, I would probably recommend reading the guide for the bride.
One other note…along with time being important for the wife, a good lubricant can be as well. I would recommend Astroglide (which you can buy
discreetly at Wal Mart if you use the self checkout line!

) or coconut oil (which is solid at room temperature but much less awkward to buy!). It really can make a difference for the honeymoon…
Approach the wedding night and honeymoon with an open mind–and, I think most importantly of all, a sense of humor. God’s design can be surprising!
