I am a Ler, and identify as Dominate sexually. My sexual enjoyment comes from controlling the responses of my partners. I am most certainly not one who finds satisfaction in being placed in a submissive roll sexually.
I'm not very ticklish, and don't get much from being tickled, on the level of the physical act.
I will however hold that as a Dominate one cannot fully understand and appreciate the roll and be fully skilled at it without having experienced what it's like to be acted upon, and thusly, I see valuable experience and knowledge in the lee roll, but that is a rather meta-enjoyment in comparison to the direct one that you speak to above.
There is also an aspect of fun in the risk of loosing control from the competitive aspect of play, or trying to continue controlling my partner even from a seeming submissive position. These are competitive aspects of play that have some value to me, and being willing to take both rolls is needful for their enjoyment. But the enjoyment is not in the direct experience, but in the risk, and stakes of the 'game'.
Speaking more directly to your question, you seem to identify as an honest switch. You take pleasure in both rolls directly, and fine enjoyment on the base levels in both rolls. Thus you can approach the play dynamic from either side and have fun with it, as it is, without, as in my case, secondary or tertiary reasons that I might allow myself into one roll. Most people that identify as Ler or lee strictly will probably have some exceptions to the roll, but will also base them around other reasons then the direct feeling of the experience.
Good question. Thanks for opening a cool discussion.
