So my current boyfriend and I have amazing sex, and he gives me the most mind blowing oral sex. But when it comes to me doing it in return I feel as if I'm not pleasing him well enough. He told me his exes head is only a little bit better because she used to deep throat, but I honestly can't do it.....is there something I'm able to do to improve my oral? Or help me be able to deep throat and calm my gag reflex?
