Seriously? You think masturbation and sex are interchangeable like that? Really?
If that's the case, why aren't we all alone in our rooms all day? I mean, there's a great deal of overlap but they're hardly interchangeable activities.
I think we are in agreement on that. LW said that after 5 years of dating someone if all you are doing is masturbating its time to move on. I agree. If masturbation has completely replaced the desire to actually have sex with a partner instead of a toy, you may want to re-evaluate your life/priorities
