Im a sexually active heterosexual male who just tested positive for hsv-2 from igg, and with no symptoms. i take a std test every year. should i take an preventative hiv medicine? as i read that hsv2 will raise my chances of contracting hiv?

You should determine your level of risk in terms of sexual adventure. If you have many partners and probably with sex workers without protection it is a consideration that you could discuss with a doctor. The positive Ig G for HSV 2 does not increase chances of being infected with HIV but the lesions or ulcers that may manifest may increase the chance of entry of the HIV virus.

A positive IgG test only means that you had HSV some time in the past. The only reason HSV2 is associated with a higher incidence of HIV is that both can be contracted sexually. If your HIV tests are negative, you do not have HIV and no treatment is necessary.
