I had trouble with that for a long time. To put it plainly, I was not multiorgasmic. So he would bring me to climax (or almost) through oral, and then switch to intercourse.... and by the time it started feeling good to me, he was done. So then I liked the oral, but could care less about fucking cuz it didn't do a thing for me. I tried to take oral until I was close.... and then tell him I was ready for sex. That helped. Now, after time, I can have multiple orgasms through oral and go right to intercourse and have several more.
