Update: So far out of the 3 girls I asked numbers from, I got a number from all 3 and each has sexted me since then. I didn't really care about their location as my aim was just to improve my sexting abilities so overall I would call this experiment a success. I'm not going to post the full conversations as they can be pretty long but I'll put up some key pieces. I'll try to add the convo to the other two, mainly since I tried different tactics on all three of the girls. Girl M is just pure persistence though, me essentially saying I know what she wants more than she does.
Girl L: Much younger, she turned 18 sometime this year. She is a cheerleader, gymnast and overall athlete.
Girl H: Roughly age 23, don't school and is a teacher. She was raised religiously and as such is seemingly prude, but really desires crazy hot sex to set her free
Girl M: I don't remember her age, she is a former model and has 3 tats (just got the 3rd today):
