35 and never ever had a boyfriend here. I have never ever been in a relationship here and would LOVE to be in one.

same here...... 37 and never had a boyfriend

Ok, so let's see.... firstly, the easiest meaning - you badly need to have a boyfriend! now...
It's an outlet for the need of physical and emotional love. it may also mean a form of spiritual search, if you think of sex in the Tantric way, which uses physical union to stimulate the energy to rise through the higher chakras to reach a more spiritually fulfilling union with nature and the cosmos. It's also a longing to integrate the opposing aspect of the self, looking for the other half to feel unity and part of one.

That you dream of men you have a crunch on, it is just natural, as you are looking for affinities and not only contrasts - after all, affinites are the most important thing in real life if the relationship is to last. And if the dream feels great gooooooooood for you! I actually think these dreams are a bit like candies given to good children to keep you happy while you are still looking for Mr. Right....

Could one of the ones I dreaming of be Mr Right or not?

Could be, but then it could just be a metaphor..... you should analyze how they are in real life, and if you think that any of them has got a real chance or not..... be objective!
I get a feeling you'll want one with brown eyes and curly black hair.......

There are two in my fan club that meet that description. One lives here in North Carolina and the other lives in Detriot.
