tell them/show them
my last gf was really bad at giving head, and even worse at using her hands
so i just worked it into her, literally
held her hands down, tied them up etc so they were out of the question
and basically just rammed it into her mouth until just before she couldn't take it. first, she would only put my head in her mouth, and by the end she was going nose to naval quite easily.

it sounds crude, but i went from "oh jeez, shes gonna do this again.." to "cant wait for her on her knees!"

practice and persistence
she gagged the odd time but i just made her feel good about it until it got to the point where i was full on face fucking her and finally receiving good oral pleasure!

A gal has to have a goal...

What an old thread! Great entertainment in this one....

My wife can DT and do it any position/hardness/angle of any porn star after practicing. We were watching porn one night when we first started dating and she asked me if I liked what the chick in the movie was doing. She practiced without telling me and then just one day did it.

Have to say that I do like it, but really nothing to write home about. She is the only girl I've ever been with who could.

A nice sensual bj is awesome. But so is a good face fuck too. Each is different, each is good.

Yeah I've had it done once, it's really strange because the one girl that could and would DT was also the only girl who could even get me off with her mouth. Some others I've been with wouldn't even do it, or just were bad at it (no enthusiasm, uncertain of themselves, no eye contact, looked bored, or didn't know how to keep their teeth "sheathed" properly, ouch.)

There wasn't anything particularly mind blowing about being DT'd but I think it's just a clue how they really enjoyed doing what they do down there that they'd make the effort to learn, and it's that enjoyment that makes it better.

NGR - no gag reflex. Oh yeah! Giggity!
