OP, how are we supposed to help you, with no track record of reviews or posts should we just guess which WG's you would consider good looking? Most guys have a type, be it black, asian, tall, short, fat, thin. Some of these things may add to a woman's attractiveness (to you), and would help narrow things down. But good looking is always subjective.
Many independant SP's do not have a cum limit, but will also not advertise an unlimited cum policy, as you are paying for her time. If you regularly want to cum more than twice in an hour, just bring it up in comms beforehand.
