absolutely. Each in their own way. There are maybe 5 classifications of psyche / response into which most can be grouped, then there are the exceptions which defy definition. Some of the exceptions are exceptional in a good way, and some are exceptional in a not so good way. Most are VERY responsive, a few are frigid, and a small number are spicy-hot responsive. Sometimes I wonder what I did. I think I know.
Vary technique to learn what is "best" for each case. Ask what they like, they always tell. Sometimes one can be a teacher too. Size very important. Rhythm & timing. Proper charging. Lather, rinse, repeat.
