I agree with you, harassing and coercing a "yes" in any situation, sexual or otherwise, is still force, and it isn't real consent.

I was recently observing a children's court hearing. A number of the kids were taking a plea deal they had been offered. One of the kids was really quiet and reluctant when asked if he was accepting this deal of his own volition and if he had been forced to say yes. The judge would not accept his plea as long as he seemed grudging about it. It turns out he felt bullied by his mother and his lawyer to accept, but didn't want to because he felt he really was innocent of the charges. The judge was clear that being bullied and coerced into saying yes is not the same as consent.

In a bedroom(or elsewhere), when faced with a larger scarier person, or when feeling physically trapped, or even when just being drunk or feeling really confused and pressured are the times when it is easiest to be coerced and bullied, and harassed. It isn't some mystery. It doesn't matter who it is asking,or who it is saying no... or staying silent and crying through the whole thing, if both people are not wanting the activity and enjoying it, then it needs to not be happening.

I am sorry this happened to you.
