Though this study is conducted by a woman for women, it has just as much relevance in the gay/msm community as well.

Abstract
Nonconsensual condom removal during sexual intercourse exposes victims to physical risks of pregnancy and disease and, interviews make clear, is experienced by many as a grave violation of dignity and autonomy. Such condom removal, popularly known as “stealthing,” can be understood to transform consensual sex into nonconsensual sex... Ultimately, a new tort for “stealthing” is necessary both to provide victims with a more viable cause of action and to reflect better the harms wrought by nonconsensual condom removal.

There are a few forum posts talking about this, but they were before the common awareness and availability of Truvada (PrEP). Of course, PrEP doesn't address the health aspect of this violation, as other chronic STIs can be spread. But it is an added layer of protection. Additionally, people posted their own experiences about this. The posts had a lot of views despite the few replies (31k views / 20 replies), which makes me think more people know about it or have experienced it firsthand.

If this happened to you, you could have legal options. And if you are doing this to others, you should stop as someone could bring a sexual assault charge against you. And being labeled a sex offender in America will destroy your life.
