First, don't be chicken-prostate stimulation is awesome, second, u need to keep fcking right up to the edge of cumin for a while and then let it rip and it is awesome, Anotehr-not very popular option is to lay off fcking for a lil while and that builds up your excitedment and intensity. Another trick is to fck in a cool place like on a beach or like in your parent's bed LOL
