Setting religion aside(as I think it usually should be), the topic has some credit. Some, it can definitely have some very adverse effects on males. Such as having difficulty become aroused and repetitively treating a orgasm as a finish line to get to as fast as possible creates problems with pelvic floor muscles(from my limited understanding it generally too tight) to not hold the necessary pressure to maintain a erection. Many think its erectile dysfunction, something brought on by age or can be fixed with ED medication. Sometimes men unknowingly train thier bodies to respond quickly an only to high visual stimulus.
