@ericmacson Thanks for your response and thoughts!
Yes, aromas are a big part of it for me but more so, the restriction. Really, everything about heavy rubber- the feel, sound, smell, the tightness and the taboo of doing things that are unusual and even potentially risky are what drive me to play, and then repeat. I've written other places on Zity about my dalliances into rubber, enemas, e-stim, sounding and cath play, etc. and will probably continue to share from time to time. I still have fantasies but my actual play has dwindled to local stuff and mostly solo experiences.
Combining play genres has been beyond next-level for me and the stacked sensations, when properly managed, are what it's all about. Nothing like being well secured, hooded, wrapped tightly in multiple layers of inescapable rubber catsuits, etc with breath control of some sort - while trying to ride the sensations of an enema going in and your cock being milked relentlessly by a machine. Knowing that a very well trusted Mistress is in total control is part of it but that (for me) is more of a safety net, it takes the worry away so I can focus on the experience. If I could be floating in a sensory depravation tank and enjoying some light, conscious reducing stimulus at the same time... Pain, tickling, the smells, the edge-of-orgasm sensation - all while drifting in and out a bit. Wow... writing this I'm thinking of booking a flight! I thought that phase of my life and erotic journey had passed...
As to the breathing part: I enjoy aromas, some restriction either via a "bubbler" or bag and have occasionally submitted to a machine to control the mix, rate, etc. Certain masks are hard to tolerate but I've found that a thin latex hood with an open face as a base layer and then a proper breathing cup built into a full-face mask that straps on solidly is the best. Just knowing as I peer out from the visor that there is nothing I can do about whatever Mistress chooses to do next (within limits) is a BIG part of the trip. The ultimate submission I guess. Watching a knob being turned and my brain & body entering another place as a result... On occasion, I've drifted into unconsciousness and when I awake (usually within moments I'm told) I am frustrated that I might have missed something!
I have an acquaintance who I've been present with while he went into "full rubber" mode and submitted to some serious invasive play. His routine involves a heavy Fetters bondage suit with a custom molded full-head rubber hood that locks on, tubes into his sinuses, mouth blocked by an inflatable gag - WAY too much for me. I tried the hood during a session for about a half-hour one day... Nope, couldn't give over to that one.
I'm a legendary backseat driver and in these situations we have to reach an understanding in advance of hard limits - and this involves serious trust. Not something that comes without time and effort. I never did this kind of play alone or with amateurs'. It can be dangerous (as many will attest) and any mistakes or going just a little too far can have life-altering consequences.
