This is just what I did, surrounding my own issues, just making shit up on the fly. Essentially every time something bothered me, or triggered me? I'd do it more, on purpose, to trigger myself into nudging the boundary further away/ increase what I could do without wigging out. Kept playing with it, and poking at it, as things came up.
Physically - Oral Sex
Gave my mouth a helluva lot of sensory experiences
- Talking with my mouth full, or around ice, or under water
- Singing ditto (mouth full, or around ice, or underwater)
- Eating while walking (That was unexpectedly difficult. When I found that out I refused to eat sitting down for a few weeks, and started carrying lolly-pops and sunflower seeds to really trip my brain out!)
- Playing with my tongue (from flipping it upside down, to spinning spaghetti, to counting my teeth, to clicking).
- Playing with my face (blowing my cheeks out, sucking them in, Elvis lips, etc.)
- Different food textures
- etc.
Gagging
- Trained my throat to swallow thick liquids, to pills, to whole grapes, etc. (I actually researched how drug-mules train themselves to swallow balloons).
- Brushed my teeth & tongue with a washcloth (ironically, works better than a brush).
- Used Chloraseptic (mild topical anesthetic) when necessary.
- etc.
Breath Control
- Swimmers tricks ((One of the primary rules of swimming is that if you can talk? You can breathe. I've actually always used this with panic attacks... But they also came in handy when dealing with my oral sex hangups.)) From gargling to "gulping fishes" (that mixed air & water choking feeling), to snorkeling, to rebreathers. Anything that creates the need to breathe weird, on purpose.
- Singing.
- Whistling
- etc.
(Lastly) Once I was completely copasetic with all the non-sexual aspects of oral anything and everything I could think of... I went on a fellatio mission.
- Researched everything I could about it (lmao, before Internet! That was an adventure)
- Talked to a bunch of people (guys mostly, gay guys even better).
- Took lessons / Practiced with friends
- Learned to breathe through my nose (that was a lightbulb moment! Shazaam. LOL)
- Learned to flip a condom around in my mouth / how to put one on
- etc.
