As I understand it, women who make ads get flooded with creepy emails and dick pics, so they only go with 1 out of a few hundred guys who offer. If a guy wants MF sex, its better to just make a post for it. The biggest fear girls have about CL sex would be the creepers, and there's not much threatening about a 26 year old virgin. If OP had a well written ad, and a picture of him smiling, looking normal and pleasant, I'm sure he would get some eventually.
Still, prostitute is still the best way to go. Johns never get arrested for it, and its just so EASY. Respond to an ad now, solve your problem in the next few hours. OP, here is the backpage for where you live. Look over the menu and put in your order.
