It is not wrong for you to feel as you do and put it out there to him at the right time. These discussions can be tricky and each person has different needs around this. You may have a higher sex drive than him, but you also need to feel loved and cared for both emotionally and sexually. I would speak to him, but not around the time of intimacy....a romantic dinner or quiet time together. I would ask him what he desires around intimacy between you and then share what you desire. I hear that you have spoken about it before but I believe not in the way I am suggesting. More as a way to get closer and find out what the other desires and how all needs can be met.
we know you go personal...so go easy on yourself. He has let you know where things are so try and be patient and gentle and things will go ok.
