How you get the sex is up to you. At your age, I'd suggest not going strictly for the providers as you need a social life & at some pooint you may just find the girl of your dreams. Meanwhile the professional companion will keep your sex drive releaved, you skills honed if you are open to it, and when you do go on a civie date you'll not be horny out of your mind & be able to actually get to know them. Another point is you may have learned by now & if yout you should... to separate the hormonal high post sex from love. This is an important point in favor of hobbying or otherwise sleeping around.
Do keep you hobbying under control. I would recommend you try to maintain the same budget you have now... and see how that goes. If it's not working, after a couple of months, cut back. Might even take a month or 2 off while you get settled in your new life. NEVER spend the rent money, groceries, car payment, or even some savings which we all must do. It is easy to binge. There are a few guys who have made horrible $$$$$$ mistakes.
The hobby does not have to be life long... and providers often are not life long... it is a stepping stone for many. Or a temporary step between others.
With the right mindset, you could be in a good place. I made mistakes at your age... gotten invovled with women who I should not have, which took me off the market when I should have been datng widely... and I'd have been better served with the advise I have given here.
