for me,
quite simple, often i have to ask myself,
do i want a cewek with good face but poor service
or do i want a cewek with ok face but good service?
often, if one can find one cewek with good face and good service the very first time, that guy is in good luck....
for me, i often choose the second option. no point at times having a dead fish...still remember the time when i bonk a sweet looking cewek, all i can hear the fleshing thumping each other and the soccer commentary sound only
