Teak i asked you abotu oral sex risks and you told there were not any risk at all, but anyway do you know something about the relation between HIV and erythema or periodontitis as a sympthom? if someone is infected does this sympthom take place in the early stage of the infection , say for example one month or two after the exposure, or this kind of sympthoms take place in more advanced stages??thank you so much. This question is regarding gingivitis as symthom not as a risk of oral sex transmission. thx
