Exactly, this is non-consensual sex. EOM ... Stop.
This is "stealthing"
This can also believe it or not be done by a woman in return. How? I had a buddy in college whose girlfriend poked holes in his condoms without knowing.
Now this is far less severe then sexual assault, but it is drawn from the same toxic pool called "non-consent".
There is no gray in this, as this sits on the foot steps of "rape" and sexual assault.
I am sorry you just get all the "special" men out there. It is irritating as fuck to observe.
