Tell her about your likings and dislikings in your life and about your family and also ask her sam things about her. Then also plan your life primarily and come on ane concent. Then start romance, starting with deep kiss and suck her upper lip and tough and also continue to dislikings your hand on her boobs and other where you desire and also put her hand on your panis and go on. If she desire more then love her dislikings as this may be her first time.After tiring go to deep sleep to become fresh for next more beautiful night.
My wife and I discussed this before we were marrried and decided we would aim to just snuggle up together but would be open to doing more if the other was. It is a bit scary, you have both hopfuly had a great day and don't want to do anything to spoil it.
This was the case for honeymoon too, just taking time to enjoy each other, you have years to have sex, make your wife feel special and don't go on about sex in a "when" kind of way. Be open and honest about it all.
