Hi. I have read many articles regarding oral sex. A lot of people have been sharing their tips on what to do after giving oral sex. There's one thing that confuses me a bit. It's about using the mouthwash. Is it true that it is a must to rinse your mouth with alcohol-based mouthwash so that the bacteria can be killed? Or simply rinse your mouth with water? Because some of the articles stated that do not use mouthwash, and some stressed on the use of mouthwash. Hope you can help to clarify on this matter. Thank you.
