I've only been sexual with one other guy besides the I am with now. It takes practice and patience if you want to learn how to swallow cum or be successful at deep throat during oral sex. Over a month ago I met the guy I am with now and he is still trying to figure out the gauge reflex. I told him it may take some time but just go at your own pace and be patient. When I began to learn how to deep throat as well as swallow cum I had to give the guy I was with several blowjobs before I felt comfortable.
