There is a difference between being disrespectful toward your desire to wait, and voicing one's own desires about sex. Clearly he does respect your desire to wait, because he is still with you. However, he has needs, too. It's important for him to be able to communicate that with you, and for you to listen and respect his needs as well. It doesn't mean you have to give in and have sex before you are ready, but it does mean that you need to acknowledge his position here. You are in a relationship together, so both of you have needs and expectations, and it's important that you both put effort in to make the other person feel like their needs are important.
