I have a lot of internet buddies and friends, some of them women, but recently I've been having feelings for most of them. I get to know them and I want to be with them. Right now if anyone of them asked me to date them I would, except for the ones that are under age, even though they don't live anywhere near me. so I ask, is this normal?

I think it's normal to develop a fascination for people online. It's pretty anonymous, and you only have to disclose what you want others to know, so the dream is usually far greater than the reality. Keep it in check or you'll come off as desperate and/or pathetic.
The other day I said I had an interest in her and wanted to know if we could meet up sometime in the future. She said its a good possibility.
That's some good sounding advice. I intended to date her before I just jump into a serious relationship.
Online, we tend to build up a picture of how a person is like. They can become a certain way in our mind and this can be misleading because it's easy to cultivate an online persona that seems genuine enough (especially with the comfort relative anonymity brings) when the truth is far from what we've imagined. So caution is good...but then, even knowing people "IRL" isn't a surefire way to fully know someone, is it?
It's completely normal to have feelings for people online. It happens ALL of the time!
I used to play World of Warcraft a lot and I would often have long vent convos with people. It would be nice to consider them freinds but even a guildy or 'raiding relationship' is barely an acquaintance.
