As a sub in some sense since my teens I totally agree, you want to try more, learn more, get to know more people within this rich vein of eroticism and life. I sometimes try several times to achieve something - a new twist to my fantasies, a new kind of bondage, enduring things harder and longer, kneeling to my Domme - and whether doing it on my own or with someone I'm spurred on to try again, while the turn-on of less "advanced" things is still around and not depleted at all. It's sometimes like diving into an underground lake.
