My friend used to volunteer at an LGBTQ support shelter. She knew gay men who had promiscuous unprotected sex 20 years ago. Some of these people had been so marginalized by society and abandoned by their families that the connection from their random sexual encounters was the only thing they had. She knew a guy that was willing to do it no matter the risks. One day he found he had contracted HIV, and not long after he committed suicide.
I’ve been to sex parties before I was on PrEP, and the arrangement is the same. Have a conversation about testing, and if everything sounds good have unprotected oral or use condoms for penetration.
The difference is that now with PrEP this feels much safer as one of the most significant STIs is no longer nearly as easily transmitted.
