Well if you had phimosis it was a no-brainer as from what I know it can make intercourse very uncomfortable, it's really no surprise that circumcision has improved things for you. A good deal of porn stars are American and had the procedure done at birth, I don't think that's really a case for having it done though as many porn stars have difficulty climaxing and with sensitivity, many of them are fueled by viagra and the "finishing" shots are filmed separately from the rest of the act.
The majority of porn stars are American and in America most men are circumcised, not due to a religious reason but hygiene and prevention of a number of medical issues can arise in men who are uncircumcised.
Americans.
My point still stands, i wasn't arguing around the reasons to have it done, rather arguing that it does not in most cases cause an un-fulfilling sex-life.
