My boyfriend has delayed ejaculation. I give him wonderful head, and he can't cum for at least 20 minutes, and never from anything but extremely fast, hard hand-jobs.. He has never cum from sexual intercourse. He always wants me to either blow him, or give him a hand job after sex until he cums, sometimes it takes an hour..! Is he wrong in making me do this? I want him to be happy, but he won't go see a doctor about his problem, and it's affecting our sex life. I just want to have a quickie sometimes, but that can never happen, cause it takes at least 20-30 minutes for him. I can cum in seconds, so that makes it even worse.. Please let me know what can be done, and also, how long is the average length of sexual intercourse? 10 minutes? 20 minutes? I wanna know!
