Hi
I'm in the UK but have also found phone sex to be problematic. Basically it's expensive because the girls try to keep you talking because it costs more. This even happens on the cum in under 30 seconds type lines! I think it's one big rip off. The girls are only interested in the size of one thing - your wallet! Wanking on MP or sending pm's to other guys about girls and sex is far hornier and much, much cheaper!
Happy wanking, avoiding rip-offs!
