I was reading some information on the field of porn addiction, and came upon the following paragraphs, which got me thinking about related observations that could be made for those who participate in the Hobby.

 
"Our novelty-seeking sex drive:
Male sexual response follows a well-established pattern known as the Coolidge effect. As demonstrated in rats and other animals, a male will enthusiastically have sex with a female he's been newly placed with – but before long, he'll become accustomed to her, and less interested in sex. However, if she's replaced with a new female, the process restarts, and the male will once again be just as enthusiastic about having sex with her as he had been with his previous mate."

"This is a novelty-seeking behavior: a new female mate is largely more stimulating and exciting than mates that the male has been with before. The effect is so pronounced that, with new females, the post-sex refractory period of males is substantially reduced - allowing them to have more sex, more frequently. While this effect is most prominent in males, it's also been observed in females to a lesser extent."

 
So, looking for input from Ladies and Gents, what has been your experience?  

For men, do you tend to 'lose control' sooner due to the excitement of meeting a new lady, compared to seeing her a second or third time? Or does the nervousness of the new encounter tamp down the rush to the orgasm a bit, and you find it easier to orgasm the more you see her?    

For ladies (who actually orgasm with Hobby men), Do you find the newness of guy an aid, hindrance, or it's the same, when reaching your orgasm? Do you find subsequent meetings easier to reach orgasms now that there is comfort level that has been reached in familiarity?  

(I know we could all answer "it depends on the person I am seeing", but if you've seen 10-20-30+ people by now, you probably have seen a general pattern for yourself emerge, and that is what I am interested in hearing about, and why you think you are one way versus the other.)

For myself, I find I have to work harder the first time I meet someone, and each subsequent meeting it gets easier to be aroused, and also hold that arousal until I want to release. The first time is harder to get aroused, and also harder to maintain control ironically when I reach the 'precipice'. I consider myself a 'connection' guy, and it would seem to follow that as the connection builds through multiple meetings, a comfort zone is entered that allows for easier arousal and control. So it looks like I am more of an outlier in the research listed
