Sure it is a teachable skill. You can to teach anyone anything. My poor H was doing alright w/ oral but totally missed up the ending. To me if you miss up the ending then the whole process was in vain. (maybe it's just me) I had to demonstrate w/ a bj. I showed him do this, this speed, switch thing up and try this. I let hem get closer to the end result and showed him when the time comes do this. Like this. Explain if pressure is to direct it's not so good (for me personally) Stop and start and stop and start.(works for me) See I do give bj's even in the face of difficult circumstances. I don't do it never, it's just a strong prefrence not to.

I have also had my H put his hand on top of mine while I do what I do. Weird but it works.
