30 minutes are enough to connect, or not, with an SP. 15-20 minutes of intense sex are satisfying. No time to loose about unnecessary talk, just enough for sex talk. Intensity is the main matter. One hour can be too long. As it is less expensive than an hour or two, I can see her more often. Unfortunately, many SP and agencies do not offer less than one hour. Hobbying becoming more and more expensive, I regret that 30 minutes is not often available. Many SP would like it because one hour can be very long for them too. I am not rich enough to afford hobbying too often. I prefer to pay my food, rent and bills! I am amazed when I see so many customers paying themselves 2-3 hours sessions many times a week or week-end. I guess that some of them must be in debt.
