Yes, I am a black belt and I only started learning TKD since I came to Korea nearly 3 years ago (been doing TKD for about 2 and a half years).
At the dojang I just left, the classes are pretty full on most of the time. I was a bit of a dojang celebrity being a foreigner and a female at that.
Often Fridays there would games and one of the sabeomnims would set up 2 teams 'Heo Sabeomnim', and 'Samantha' or as he would say 'Sa man da'.
With the same sabeomnim, when it came to sparring practice days, he would get me to spar against him, or set it up as a challenge for some of the older kids to spar against me,at about 172cm (and I look taller) I am pretty intimidating even to some of the 15+ year old boys.
