First of all, try to find the source of the question. If you find the source, you get one step closer to finding the answer yourself.
In the meantime, the answer is yes. Not only opposite sex, but all life - women, men, adults and children, birds and foxes. You become attractive to LIFE, because you are life. The same way women and men find babies, before they have developed personality "cute", they find enlightened beings "cute". There is no rational reason, just "something about them". You are everything any person is looking for, whether they know it or not. I am not going into detail to explain how this attraction is expressed, to not feed your mind with some image of "Enlightenment" and what it entails - it has been done so many times already (most are wrong).
The attraction from opposite sex is absoulutely there, it is totally up to being to act on it or not. From my own experience, I can't see any permanently enlightened being going around having one-night stands with everybody. Whoever comes into contact with this, on a romantic/sexual level, falls in love on the deepest level of their being. If they lose it, it breaks their heart. I can't see myself ever doing that, of course can't speak for the others. Deep desire for a meaningful romantic relationship can be there, but it is not exactly desire as you might understand. It is seen as an experience, whether one chooses to have it or not, is up to every being themselves.
A realized being, let's say a man, is everything a woman is looking for, on the deepest level. The "unpleasant" body odors are gone, replaced with excess amounts of pheromones, unconscious immediate attraction to women. The full relaxation of the body in the permanent meditative state is expressed in the eyes - whether one sees it consciously or unconsciously, it creates an immediate attraction, across sexes. The natural non-neediness, no desires, is irresistible to women. It is kind of same when you are looking for a relationship or a partner, you attract the people that you don't really want. But when in a relationship, and this initial satisfaction and love (piece of pure love experienced for a short period of time if one is still identified with ego-mind) becomes subconsciously attractive to opposite sex. I guess it is commonly interpreted as "you are shining". When being is permanently liberated, this shine is natural, it needs no outside experience to have it. It is permanent, and it is obvious.
