He has insecurities about you all.
He doesn't feel special.
I think he thinks you could get off with anyone, anywhere- which may be true - but you are not interested in that right now :-) and he wants to feel like an alpha male.
Reinforce how good he is to you....and how good only HE makes you feel....and don't chat away about all the things that turn you on unless it's him.
Other than that, you may be a sexual mismatch....you are ready for action and he wants to think about it...if you all are made for each other, recognize these differenes and work with it. If so...keep trying.
He could finish in your mouth perhaps and you can tell him how great he tastes and only him - hey, just a thought.
