I know what you mean, I have felt that way myself, but I don't think it's a gender issue as such, it's to do with how connected you feel to your body. I suppose it's natural for people to be frustrated by the physical limits of their bodies, being blessed with imagination, but it's what you do with with what you've got that counts. I think pretty much everyone gets this feeling at some point, some less than others. I really do know what you mean, sometimes it's as if I'm viewing my life from outside a bubble (a lot of my dreams incude me in this perspective, too), doing things purely for the new sensations it will bring, or I'll look over a landscape and nearly give in to the impulse to take off and fly over it before I conciously remember that I can't. As I said, I reckon this happens to a lot of people.
I have felt a lot less like that as I've started to try and take control of my life, make my own decisions and all that. I found this feeling of detatchedness got me the worst when I felt like I was just caught up in the machine of society, like my next step was always obvious. Now, this next bit is going to sound odd, but I found it quite useful to see my body as being like a mech (for all you non-anime-geeks, that's a giant humanoid robot piloted by humans) that I (my real self) controlled. No, that wasn't me, but I was responsible for it's upkeep, how it looked, and I was the sole person responsible for making decisions that it could carry out. Over time, the body and the self became much more integrated and I feel more real now.

Now, having wierded-out most members of the forum...
Find people you can talk about this with. It sound like you're after meeting new people anyway, and so maybe getting talking about this in real life would help relieve some of your feelings of isolation. Even just spending more time with people in general might help. Join an evening class, a sports team, volunteering, whatever floats your boat. Failing this, find a councillor you can talk about it to. I'm no expert on how to cope with this, so they may have some better strategies.
The way I see it is I've only got this body for the amount of time I'm on this earth, and so you have to enjoy the sensations it gives you while it can. It's OK to be wild and free with the animals, or the stars, or the grass and trees, let go of the human facade for a little while sometimes. I'm happy with that.
