There's nothing particularly wrong with lust, sexual attraction, desire for connection, etc. It's all part of simply being human. Why would you assume that the teachings of the Christian bible are correct, not in just this matter, but any other? Why not any other scripture? Buddhists, for instance, would say that any desire prevents you from progressing spiritually. Satanists (me!) would say that no desire is inherently wrong, and that it's how the desire is expressed, and it's whether it overrides someone else's autonomy that makes a thing right or wrong.
I don't view paying a prostitute for sexual services as being inherently wrong. It's wrong if you've agreed to sexual fidelity with another person (terms and conditions apply), and it's wrong if you're using a prostitute that has been forced into sexual labor. But if you haven't promised a partner (or partners) that you will be sexually faithful to them, and the prostitute is in the field willingly--or, at least as willingly as anyone that works at any job--then it's not really any more wrong than, say, paying someone to make a meal for you when you're hungry. Labor is labor, regardless of the nature of the work.
The first step to overcoming this 'problem' is therapy. You want a sexual and emotional connection, and you feel like you're unable to find it otherwise. You should find a licensed psychotherapist--not a member of the clergy, not a life coach--and work on why you have problems finding that.
