SA (Seeking Arrangements) most certainly enjoys the ranks of 18-19 year olds, and seems to feature a disproportionate share of F.I.T. students in NYC. For better or for worse, I have entertained the likes of 19, 20, and 22 year old students from F.I.T. My experiences were mixed, but all 3 had plenty of classmates and friends who were also on SA as well. With enough time, effort, and $, patience pays dividends.
