Personally I find it very distracting NOT to masturbate for several days in a row. Maybe itīs just me, but it is much easier to concentrate if there is no sexual energy piling up in your brain - unless Iīm doing someting that requires that sexual energy, like working on an erotic drawing or story.
If you spend all your money on porn I admit there may be a problem. Iīm no fan of porn because there is so much abuse going on in that industry. Just use your imagination.
Or do you think you are no longer interested in relationships because you masturbate regularly? Maybe you need to adjust your view on the other gender - itīs not like itīs only there so you have something to err... express sexuality.
