Sexual Consent

I have an obsessive worry that I will be sexually assaulted. Today I was looking at a forum elsewhere and I saw a thread about oral sex. I clicked on it despite the fact that I knew I would likely be triggered by it. It was about a guy who didn't like doing oral because his girlfriend was stanky. One of the replies suggested he wash her down there in the shower under the guise of sexual stimulation.

...obtained by deceit in respect of the identity of the person or the nature of the act

Partner lies and says they are washing you down there because they want to sexually stimulate you when in actual fact it's because you have a bad odor. Technically speaking it fits the legal definition for sexual assault.

Now I'm afraid that something like this is sexual assault, though it technically does fit, I don't feel it is. Though I can't think of why it wouldn't be if it fits except that I don't think someone is likely to feel violated if this happens to them. Then I get afraid of just letting it go in case I'm wrong, it is sexual assault and I dismiss someone that has had this happen to them or do it myself. Why did I have to look at that thread?
