@Annaharts2012,
This is what I saw in your post: He is naked and you are clothed. He wants you to taunt him about his manhood and question it. He needs 20 minutes of that taunting about that lack of manhood to be truly sexually aroused. These all point to signs that he wants you in control while he is submissive.
If you check out femdom literature you will probably find all types of ways of taunting men about their manhood, some mild but some of it quite severe like dressing him like a woman or cuckolding him. Much of it has to do with a psychological need of the submissive person to feel dominated or humiliated. Some people find it quite emotionally fulfilling to not be in control or to be treated in that manner because they don't feel worthy or some other reason. Even US Congressman can have those fetishes. There was one recently that like to be dressed in diapers which is also a variation of having the woman in control while the submissive is not a man because he is still a child.
Whether your boyfriend is looking for more is something you will have to talk with him about. Clearly you are finding one scenario to be quite boring. Find another scenario and surprise him with it. Branch out from his scripted lines. Tie him to the bed so he can't complain and then find other ways to question his manhood. Make him wear women's panties because his penis isn't large enough to be a real man's organ. See if it turns him on. Talk about it. If what he is really looking for is to be humiliated about being a man then there are lots of ways to do it. Find some erotic stories about women controlling men. Read them together and see if you find them interesting or not. But first and foremost, don't do something you are uncomfortable with just because he wants it.
