Smiles....after a lil creative editing, i think i found at least one answer...that imagination is just that, imagination...you can experiment within the comfort of your own brain. if you feel shame, it's yours, and yours alone, and you don't have to share.
All of my Lifestyle activities have been online. Within my own imagination, i've explored on my own, and the exploration has allowed me to find and set my limitations....i know what i can do now, and what i DON'T think i can do...my limitations include things like scat...i'd thought about it, but when confronted with it mentally, within a fantasy, i shut down cold. And so now i know...i won't go there.
"When it leaves you feeling shame after, what is that?"....it seems it me, the shame is within your mind, your conscience, setting your limits...
