First of all, congratulations to your coming wedding!
Well, my wife and I were virgins until our wedding lunch reception. (Yes, we don't have wedding dinner, but just a simple lunch reception with friends and relatives. So by 2:30pm, we were alone in our Honeymoon suite
I made the mistake of penetrating her after just a few kisses. Years later when we recollected that moment, she told me about the pain, though she did enjoy that "first time" (probably just to comfort me).
As we had the advantage of time, we went for a meal, then walked by the beach, then headed back to the room to ... you know what...
, she started to enjoy our "round 2".
Then we opened our gifts and then showered together and "round 3" before going for dinner. Finally, after enjoying the night scene together, we had our "final round" before retiring.
That day was memorable to us even until today.
The conclusion of my story is, enjoy. Yes, first few intercourse could be painful to the ladies. The "blood testimony" on our bed sheet silently told of the pain my wife endured.
But the other moments like sharing romantic meals together, enjoying beautiful sunset together, showering together, etc had allowed her to relax, which contributed to easing much pain.
Year later, today, oral and manual fingering had become a must before intercourse. I don't know how you view, but willingness to go down for your wife gave her much assurance about your love. You may like to include this and manual fingering in your foreplay.
Well, so much I typed and hope it benefits you.
