My boyfriend seems turned off...am I being too easy?

I have been with my boyfriend for 7 months. He liked me alot at first and would come to my house every day for sex. We were friends for 2 years and one day we slept together and he kept comming back. Now he seems have lost his drive for me. One night I just started touching him. I did that for 20 minutes and he woke up and we made love. He said he didnt like oral done ON HIM. One night I did it and he didnt stop me. So now he will let me do it but he wont ask. Im always the one who ask. Why doesnt he ask? Why doesnt he ever say no. He claims he doesnt like things but he lets it happen. Why does he go to sleep but is never annoyed when he is being touched and played with in his sleep. If it were me I would be furious to keep being awaken. Is he playing games. Ages 40 and 42
