Boyfriends who want sex but us girls don't

Im 18 and have been with my boyfriend for two years now. I love him but Im just not ready for sex. He wants to do it. I feel bad because he wants to do it and I just cant give myself to him because im not ready. He is totally fine with that. What should i do? Him and I have done other things but sex. I want to do anal instead of vaginial. Any tips?
