When it comes to the prefered balance of sexual dominance there are three types of people - subs, doms, switches. Sounds like you are a sub.
Subs want to be submissive.
Doms want to be dominant.
Switches like it both ways, though they may have a preference.
There are people of both genders which fall into each catagory, though it is not a myth that women are more likely to be subs and switches. If you browse on the net you will find that you are definitely not alone, there are many male subs, an entire genre of femdom, extending from mere female dominated sex and spanking to more extreme kinks such as face-sitting and strapon role-reversal sex.
You will find that most women will be happy to try and fullfill your fantasies at the milder levels, they may even be happy to experiment with more kinky stuff (I am sure even women who have no dominant tendencies would like to experience what its like to 'take a man' once). However, if you read on this subject on the net you will find that many men like you find it very hard to find a women that is genuinely into dominance (not as an occasional 'variety is the spice of life' addition to regular sex).
It is much easier to find girls who are into being submissive, perhaps this is because sex is intrinsically a male-dominated act, even when a woman is on top and gains increased control the penetrator is the one who 'takes' the penetrated - which is why role-reversal strapon is such an effective way of turning the tables not just psychologically but physically. This is maybe why there is a taboo about violating steriotypical gender roles (which do in fact bear some relation to physical reality). But there is nothing wrong with you, you should embrace your sexuality, and there are certainly some women out there who could fullfill it (not merely by doing it to please you, but because they enjoy it too).
Personally I am a predominantly a dom, but I also have the occasional submissive fantasy, so I understand what you are feeling. Dont be scared of articulating your desires to girls, if they are not doms they will probably still try to satisfy your needs so long as you are trying to satisfy theirs too.
