When I was young, I absolutely lusted after blondes. Like yourself, I had only been involved with dark-haired girls. Finally it happened. She looked like the highschool version of Heather Locklear, I was absolutely entranced.
But then I actually dated her. In bed, it was largely quite nice, but mentally and emotionally? Oh, man, was that girl damaged. It completely broke my interest in blondes. Being unusually rational at the time (me, that is), I broke things off. Another guy I knew expressed interest in her. Told him I thought it was a bad idea, but if he really wanted to, I'd do what I could for him. They dated for about six months, and when I heard from him again it was about how crazy she was.
Since that point, it seems like almost every one I've met IRL was either nuts or ridiculously snobbish. Now I only enjoy them periodically in digital form. Tara? Mild crazy on display here in CS, but not enough to throw a big red flag. In most of the VNs I've played, though, blonde really doesn't work for me. I can't even remember the last one prior to Tara, and I honestly have to give the majority of the credit to the artist. That Jaye/Tara flashback was incredibly well done.
