You need to be loving, caring, and let her know that you want to enjoy life together and with that in mind , is the enjoyment of making love with each other.  Explore the ways that make her enjoy it and then show her the ways that you want to be pleased sexually.  That way she will be more receptive and will gladly try to please you too.  As the others said, communication is very important so you'll understand how both of your needs will be met.
