How can I stay more focused on doses? I counted down once, which worked, but its kinda hit and miss.
Also, could I load (rap) songs into the background to help me focus?

K, just tried Orgasm and it was one of the greatest things of my life. I was only able to get 7:30 because it was so strong. Ok so what I did was count down from 450, which worked wonders. Heres the breakdown 0:00-1:00 nothing, some light sensations 1:00-4:00 some involuntary muscle spasms in my leg...
