it depends which day and what time you called, weekends and weekdays after 10pm most of them don't answer.
if you going for a punt make sure you have 4 other plan B, most of them do not play with the rules...they are not obliged to.
I can suggest anyone..depends on your taste...myb others can.
do a detailed search to get a nearly perfect match for your likings.
personally, I go for English girls, as they are trustworthy.
I don't trust most europeans.
don't rely to much on feedback, some of them are fake.
maybe the guys can give you a better advise han me
