When it comes to bbbjcimsw etc it is not really teachable. For some women there is an "eeewww" factor that they can't get beyond. My partner is great at bbbj but won't let cum anywhere near her face let alone her mouth. It grosses her out. Then my previous GF couldn't get enough with her instigating and swallowing 2 to 3 times a day whether it be in theatres, the car, at the beach, on the couch with her family in the next room. She was genuinely turned on by it and that can't be taught... I miss her...at times...
