I don't see it as adolescent at all. I see it as Allah giving men what they seek after in this world, only minus the negative effect. There are a whole lot of men who try to be "playas" and "pimps", and try to juggle more than one woman at a time. Some men cheat on their wives or long-term girlfriends with a woman that they really don't care much about. Even with polygamy, when a man can actually get more than one woman, it is not without it's stresses and strains. I think men would gladly have two or more women, if they could obtain them with 0%negative impact. Even a faithful and loyal man's eyes and thoughts stray to other women, even if he does not want to act on that. What if he could though? What if he could get that other woman, and not have to worry about the guilt of infidelity, losing the woman he really cares for, ruining lives, or breakng any hearts? How many men would really pass that up? I think very few.
The idea was that people while they were in the world sacrificed and abstained from doing things that they would have liked to do. Because they sought after the pleasure of their Creator, they sacrificed a little of the fun or freedom they could have had. This world is a place where we are striving to obtain the pleasure of Allah. The paradise, in return for the struggle and sacrifice made, is a place desinged specifically for what pleases us. This inevitably includes sexual pleasure, since we take much pleasure in sexual activity. The women of paradise are not the sluts of paradise, they are the wives of one man. Each man will have his own set of wives should he so desire it.
It bewilders me how picky we humans are though. We tend not to be able to see the forest for the trees. It is not enough that we will live our lives in such a way that there will never be another negative thing happening ever again. No more health problems, no illness, no bad tempers, character flaws, robberies, murders, jealousy, envy, homelessness, hunger, poverty, we will never be dissappointed, no tragedies, and no death. We will have freedom in absolutes. Something that we strive for in vain in this world. Here in this world we will never experience true satisfaction and 100% contentment. Here there is always room for improvement and room for more. The more wealth we obtain the more we spend it, and the more we want it. Getting good sex at home? Not really. One can always get freakier, kinkier, new position, toys, games, let's add a partner, let's add a room full of partners, wonder what it would feel like to.....? Getting good pay at work? Not really. There is always a better job, more pay, more benefits, more vacation time, bigger office, easier and less time consuming work.
The point I am trying to make is no matter what we come up with to entertain ourselves and to have fun with, it always gets boring after a while. Never enough games, enough parties, enough money, enough attention, enough material possessions, enough space in my house, never as many cars as I would like. We always search for that next level because we always plateau. In paradise that quality is gone. Things don't get old there, they don't go out of style.
All that is not good enough for us. We have to say oh well I don't like that part of paradise. Or why does it have to be like that, why it can't be like this? For those who believe in getting a paradise, the details aren't important. What's important is that we get there and avoid its equal opposite, hot little friend on the other end of the sprectrum.
