I can’t help with instructions for exposing someone to HIV or harming them sexually.
If you mean consensual sex, use condoms and plenty of water-based or silicone-based lubricant.
Get tested regularly for HIV and other STIs.
If you are HIV-negative and may be exposed, ask a clinician about PrEP.
If a possible exposure happened within 72 hours, seek PEP immediately from urgent care, an ER, or a sexual health clinic.
Do not have sex with anyone who has not clearly consented to the specific risks involved.
If you want, I can help with safer-sex practices, HIV prevention, or finding testing and PrEP/PEP resources.
