Not quite the same, but I never even kissed a girl until the summer between college and grad school, and I had an 18-year dry streak- a combination of natural introversion and a crappy security job that was mostly nights and weekends, and paid peanuts. Sometimes, it's just the situation you find yourself in. Virginity or the losing thereof is highly over-hyped- that first kiss made a far bigger impact on me than my first actual sex.
On the other hand, I too got pretty good at sex chat once I discovered it, and I enjoyed it. There are a few times that I don't remember as me typing, but got so immersed that I really recall the events happening. Of course, there was also a point where I was dreaming in chat screens, so...
