This is my second post on freedomhealth. I want to know more information to do with sexual health. thanks doctors for the information.

I am a male 21 years old.

If I had anal sex with a female sex worker in the United Kingdom in a massage parlour is it possible to get HIV. If she was positive for HIV and had been infected 2 months ago. What is the percentage chance I would get HIV infection after having anal sex with her 2 months after she got infected?

Also if I had only unprotected vaginal sex ith a female sex worker in the United Kingdom in a massage parlour, and she had hepatitis B, would I get infection from vaginal sex? what is the percentage chance I would get hepatitis B? if I did get acute hepatitis b from her, would alcohol consumption after 2 weeks make it more likely that I would get chronic hepatitis b.

Also can I ask if all NHS GUM clinics in hospitals use fourth generation HIV tests. HIV antibody AND p24 antigen simultaneously. OR do a minority still in late 2011 still use third generation tests? are fourth generation HIV tests universally used in every single NHS GUM clinics in hospitals in the UK?

thanks
