For me, it's all about the lady being into the sharing of intimacy. Sex is sex but being able to get intimate, even for a short one hour date, is where I get satisfaction from the encounter.
It's not about going through a list of positions or ticking off a checklist of sex acts, so asking what's on the SP's menu isn't important to me. In fact I hate the term menu in the first place. I much prefer that the encounter flow organically based on how we both feel in the moment and based on our particular "turn-ons".
I've only ever repeated with SPs whom I felt were into the session as much as I was. Yes, we all have our "off" days and maybe I passed up some potentially good repeat dates this way, but it's why I meet ladies in the first place, so for me it's a deal breaker.
I guess for me the saying "Quality vs Quantity" is where I've naturally moved to in this pursuit. I used to make my decisions based on seeing ladies asking for less per hour, so I could see more ladies per month, but then realised that the encounters weren't very satisfying so I started arranging fewer, longer dates with higher quality ladies and I've never looked back. It's all about the total experience, not about a quick orgasm.
So, to answer the OP, and borrowing from previous answers, for me its all about when the lady:
- Genuinely likes sex
- Is passionate, sexy and classy
- Is respectful and has a great attitude
- Is clean (including her incall) and is low volume
- Is a pleaser (as john says, attempts to make it a memorable experience for you not just get you off and out the door)
- Is organized, punctual, not flaky and honest
My two cents.
