You made a good decision going to Sheri’s for your first threesome. Have you looked at the ladys pages to winnow down which lady you want to party with? After that I would email them to see if there is any chemistry between the three of you. Tell her explicitly what you have in mind for a long party or multiple party plus an idea of your budget. You have plenty of time so do not panic or rush your decision. I prefer to reserve time with a lady ahead of time, but prehaps if you cannot decide you could go to the bar and talk to several ladies to make your decision. I had my first threesome at the Ranch last year and it was soemthing to remember.
