Yes, sex is therapeutic in terms of both mind and body. Sex is also an exchange of trust and consent (in the case of escorting trust and consent is quickened by a financial component).... Seeing escorts can be extremely therapeutic for many guys. It's a form of holistic-healthcare IMO. And its soooooo much more healthier than just jerking off to porn all the time. Much better seeing real human ladies in the flesh regularly..as long as your bank account can support your hobby.. at least it won't break your stick like what can happen to porn addicts who require a combination of high-speed internet porn & death-grip to get up & get off...
Not sayin to stay away from porn..but if it's the ONLY kind of sex someone is having there's a high risk of it leading to performance issues later on down the line when the guy finally finds himself trying to have intimate time with a real woman...
"Addiction" is a contextual label and often too liberally applied eg "I am addicted to Bikram's yoga". Trust and consent are not associated with "addictive" behaviours.
As for masterbation, maybe it becomes problematic if you've self-stimulated until you're left with an insensitive bloody pulp of an organ. If that's occurred, there are other diagnoses available.
I'll add a 3 minute porn clip and fist full of lube cannot be equated with the company of an escort who blows your mind. One is like an iTunes sample, the other a Dave Matthews concert.
BTW - per the original poster's proposition --- Each time I read it, my first thought is they're "troll baiting". As others have pointed out there are sound programs to assist those concerned about their sexual behaviour.
