Let me put it like this;
Men and women are able to change their mind about engaging in sexual activity even when;
1 - they are in your apartment/house
2 - they are kissing you
3 - they are naked in your bed
4 - have already given you oral/other sexual activity
5 - are currently having sex with you
etc.
You are not entitled to a person's body just because you have cleared certain checkpoints, and for some people they can go from wanting sex in one moment, to not wanting it, in the next moment.
This idea of a verbal 'no' is troublesome because it assumes that the person who wants to say no, will always speak up and communicate this.
If someone is not wanting to engage with you sexually, yet you insist on doing so they will often 'check out' so they are not wholly there or present, this is particularly prominent with rape and sexual assault victims when they freeze, or are silent and not as responsive.
Just because they didn't communicate a verbal no, doesn't mean that they wanted it - but their body language should give you indication of this, and if you aren't sure just ask, look them in the eyes - if you're having sex and both of you are enjoying it there should be sounds, grabbing, kissing, eye contact etc.
Equally, sexual assault isn't black and white - so I understand why some of you may feel frustrated.
What Aziz did wasn't okay - does that make him evil, bad? No. Should he be in prison? Not in my opinion. Should his career be over? Nope.
But I hope that he, and many others - because this is a common experience for people to go through, especially women, and it's only so common because of the lack of conversation surrounding it.
