Knock on wood and continued positive vibes / energy or what ever source works LOL I have not gotten an STD. I get tested more than once a year and include the throat swab. A lot of times you have to request it in addition to the other. I have been in the hobby a long time. I do require protection for intercourse but prefer bbbj. I am also very active outside the hobby. My regular partner gets tested in the gaps between mine. If you are worried about discretion there are also mail in test and the results are emailed to you. It is important for all of us in the hobby , providers and friends, to protect ourselves and others.
Stay healthy and keep having sexy fun
