I am writing this to you on 13th may 2017. I had a sexual intercourse yesterday with a sex worker in Thailand. But it was a legal centre. Where All preventive measures for STDs are strictly followed. Like the girls Undergo through a medical test after every intercourse and every week there's a blood test. And the girl with whom I had intercourse was looking very healthy And it's sure there was no signs of cuts or blood in either her lips or vagina. I had licked her vagina for 2-3. Mins. Then had completely protected vaginal sex with her using a condom. And even immediately after that I washed my mouth 3 times with colgate plax and washed my lips with the available dettol hand wash. I am very much worried. Will I be the victim of any stage. And just for the information I had taken hepatitis B vaccination few years back. Now the problem is because I don't know what was her past. Or with whom she had intercourse before. And I am sure I did not feel any of her vaginal fluid in or around my mouth after licking the vagina. Please help me! I am scared! Will I be affected?
