HIV can get into his body through the lining of his ass

HIV can get into his body through the lining of his ass, even if the lining is not damaged HIV can get into his ass even if you don’t shoot your cum inside him. Your pre-cum contains HIV, and you can leak small amounts of cum before you have an orgasm. So sticking your cock into the other guy’s ass just a little, for just a short time (sometimes called “dipping”) or pulling it out before cumming is high risk. Rough sex can damage his ass and your cock। This increases the risk of passing on HIV.
Inside your ass there are fluids that contain a lot of HIV. HIV can get into his body through tiny cuts or open sores on his cock, through his foreskin or through the lining of his piss hole (urethra). Rough sex can damage his cock and your ass। This increases the risk of passing on HIV.
If there is blood in your shit or piss this can increase the risk of passing on HIV to him. Getting shit on open skin carries a high risk of bacterial infection and can lead to blood poisoning. This is true whether or not the shit comes from someone who has HIV.
