I was very nervous my first time. I was on a business trip in another city, was married to my ex and thought I'd try a whore. I'd called her number and found the price, and she sounded nice so I went around and rang her doorbell. She opened it a bit and said 'come on in then' and I did. She was in bra and knickers, stocking and high heels, and she looked amazing - blonde, big tits, long legs, young, very sexy.
I paid her and she took me to the bedroom where she undressed me (which I found later is unusual). She asked if I was her first whore and I said yes - it obviously showed! - and she then kissed me (again very unusual) and led me to the bed, where she got nude and gave me a BJ. We then 69'd, then played with one another and kissed a lot, before she asked me how I wanted her. I did her doggy at first, then mish, then she rode me, then I finished her off in doggy again. She was very sweet and kept on saying nice things about my cock and my fucking style. Afterwards we cuddled and chatted a bit before we dressed, again unusual.
It was great experience and started me off on several years of using whores. She was one of the best, a great girl for my first time. Many others I had were bored, drugged up or uninterested but there are some really, really good ones around; I eventually found a regular one in my home town who was honest, fun and a good friend, and had quite a few 3somes with her and her friends. Apart from her, I particularly liked going to brothels and choosing my girl (or girls, often I'd have two) from a line up of those on duty. Brothels are illegal in the UK but there are plenty around if you look!
I wish you luck with your first! My only tip is treat them like human beings not slaves and they'll appreciate it.
