Hi there. This question has 167 views hitherto so felt obliged to try & answer & clear this issue once & for all. Oral sex
is called cunnilingus (when a male practices it on the female) & Fellatio (other way around)...this is assuming heterosexual behaviour..similar analogies may be extrapolated to those practicing alternative or different sexual habbits..lesbians, homosexuals, transexuals etc.
The damage is different in risk ratio to the 'recepient' & the 'performer' depending on the trauma to the sex organ involved. Also the ratio of risk changes (increases) if there are cuts on the mucous membranes of either oral or genital mucosa. However, an important point to note that the HIV
virus is negligible to NOT present in fluids such as sweat, tears, feces & lesser in saliva too unless contaminated with blood or blood products. Note I have largely kept percentages out as firstly as they are small (in the range of 0.04 % to 0.005%) etc, they tend to convey a wrong picture. To put it coyly (tongue in cheek) : "it only takes one prick"! so do be careful out there..
Most importantly, the take home message is not that it is realtively safe so go ahead..it is still & will remain "pratcie safe sex
..use a condom" & /or stick to one partner!
Cheers & Good luck & wish you all a happy sexual appetite & safe sexual lives...cheers!
