As an INTj I can conlude the following:

I'm more likely to "play the field" over the net then in a socially hostile environment that is a crowded club or bar. Yes, I go out every weekend but it's the same old story where I naturally enforce my introverted nature in a place where I feel uncomfortable to be extrospective as your expected to be.

I'm still going out every weekend in the hopes that I will find a strategy for breaking the ice and conquering not so much my fear of approaching the ladies but my fear of my fears.

One problem is that I get too intuitive about the whole process, I find it very difficult to just live for the moment, throw caution to the wind and just do it.

Inaction is just resulting in more fear of my fears and more regrets of "why did I go out when I knew the way things would go?" dillemma.

Maybe I just need one night where I actually do get quite drunk, it could be expensive and bad for my health but it might just be worth it.
