What Are The Chances Of HIV Infection After Oral Sex?

Hello

yesterday night i was drunk and had a deep smooch with a prostitute involving tongue for 3-4 minutes, i have cut in my mouth. I do not know her HIV status, I am very worried as i heard that HIV infection may pass if there are cuts in mouth, I do not remember if she too had cuts or we exchanged blood through smooch. If bloods were exchanged and she was HIV positive, will i get infected? Should i go for testing ?.

Please Help


Thanks in advance
