Alright, i just jerked it today and i literally shot my clue goo 15 feet with tremendous force, the orgasmic sensation was incredibly intense too.  I think the secret is in waiting.  I didnt eject semen out of penis in about 3 weeks.  My balls were starting to ache and i had a boner for like 5 hours.  So i rubbed one out.  And sweet Jesus was it awesome.
