Hi,
I was recently in Bangkok and had a one night stand with a normal Thai girl from a club on 20th Nov 2014. I had protected sex with her which involved french kissing, after I had ejaculated, she took off my condom and gave me oral sex. Three days later, I had sex with a sex worker, she gave me oral sex without condom. She put the whole condom in her mouth and wore it on my penis with her mouth. We had sex after that. I am concerned about any HIV or STD risk and has been wanting to go for a check up. However I know that some viruses or diseases cannot be detected so fast after exposure. Please advice!
