Dear indianguy1983,
No one can tell you whether or not you should hobby, that is up to you. But at the same time, you probably understand that the world runs on averages, hunches, stereotypes and perceptions as much as it runs on specific rules inspired by stats, however interpreted or even homecooked. And many providers simply will not see guys under 30 (or even 40, as this board has witnessed) because they feel/believe that overall, younger guys are not as polite, courteous, relaxed, trustworty, discreet, kind, safe - I could go on and on but I'm sure you get my drift. Hence, rather than worrying about any of the above, these providers have simply set a rule - no one under X amount of years old. It's like the actuarian tables of an insurance company - why are premiums the highest for men 16-30, and go down significantly for guys over 40? Risk factor, my friend. You could be the safest driver in the world and be 25, but the insurance company still has its rules.
Also, with being a student there is a screening issue. Unless full-time employment can be verified discreetly and completely, how does a provider know that you're not employed by law enforcement AND also a student? Unless she can verify full-time employment at a suitable place of business, she may not want to meet with you. And, if you're making extra money delivering pizzas (just an example, please), she may not want to meet with you because of that. Providers need to feel secure and comfortable, since they are selling services that involve their physical bodies. Knowing that a potential client has a regular position of some longevity in an established place of business is one more indicator that contributes to feeling just a little safer for the ladies.
Now, in my own personal old-lady opinion, I think students should try to get laid for free, since most students generally don't have loads of pocketmoney to play with. It's good socialization training trying to screw civvies. It builds character and experience
! But if you must see escorts, for whatever reason, I guess your best bet is to keep on trying, knowing that you will get turned down with some frequency. It's nothing personal, just the way the stats work against you at the moment. Check back in another 10 years when you're putting your wonderful degree to work in a superior working environment, and you'll see that providers won't be a problem.
They wouldn't give me a Sears card when I was 25 and I still get mad when I think about it
