I have sexual intercourse with escort about 3 times a day and during sex I have to wipe off my penis 2-3 times with new paper towel everytime and it will be wet. I saw a white liquid on her vagina and also a drop fell into her belly when i put my pennis on her stomach. I checked the condom from water. but there was no leakage. Is it the fault of condom. Sould i go for PEP?. please help
