i made my first fixie with out brakes and i just kinda had to learn how, at first i was scared to do the lean forward skid. so for about a week i would just backpedal and resist the bike since i didnt have brakes. then i learned how to skip the back wheel. what i did was i went to an alley and found some loose gravel and would try it slow there. after only about 15 minutes of doing that i was able to do the lean forward.
