hrmm... well the normal jelz about 2 seconds, then i flex my pc muslce a few times.. 3 seconds.. then i bend my head to my chest to get more blood in it (3 seconds) then i grip my base harder, then squeeze the blood from my head (5 seconds)...
so that about a 15 second round trip.. though i dont do many of them,... cause maybe every 30 jelqs ill do one..
so yers, hehe, how many do u think i should do (if you eliminate everything but the reverse jelq it then i do 5 second reps)
