To plan a special night, first you will need to plan a date where the both of you are free and mark it on your calendars so you don't forget. Next you will want to plan a dinner that you will prepare at home for the two of you to have a romantic evening. Choose a dish that you are comfortable making so you don't stress out too much about making a new dish and if it doesn't turn out the way you want then it may ruin your evening. Also, you want to choose a dish that you don't cook regularly. Now that you have the meal planned, make sure that you decorate the table with nice dishes and glasses. Pick up a few candles to make the night a little more romantic. If you want to you can pick up or arrange a nice bouquet of flowers as the centerpiece.
Next you may want to pick up a little sexy outfit for after dinner. If you are comfortable with baking then you can bake a pie or cake. The smell of something baking in the oven is very pleasing to men. If not you can always cheat by buying a frozen pie and pop it in the oven and your house will smell great.
If the night is very special like a birthday or anniversary, then a gift may be called for. Depending on your man and his likes and what he already has will determine the gift. If he's been asking for something specifically, then it makes it easy for you. If he hasn't been asking for anything special, then you may have to look around a little and maybe search the Internet for a few ideas. You may want to do a "Great Gift Idea for Men" or "Gift Idea for men" search to help you find that special gift.
Now it's time to put everything together and enjoy the night. Dinner should be ready or near ready by the time your man walks through the door. That way he isn't waiting too long to eat. Enjoy dinner and wine and then move on to dessert. Next it's gift time and you take him to a nice comfortable spot and have him relax a little while you change into your sexy outfit and grab the gift. After opening his present then you can give him a little massage and the rest of the night is up to you.
