So let’s have some real talk.
And we’ll start off with this: you have never had sex with someone in which they gave full, enthusiastic, unqualified verbal consent to everything you did. Neither have I.
I have never had sex with a woman and asked, repeatedly: “can I touch your left breast? Can I touch your right breast? Can I touch your left nipple? Can I touch your right nipple?”. I just assume that if a woman is willing to sleep with me, they are okay with me touching their breasts and nipples. Equally, when I go down on a male, I assume that their consent to me sucking their penis extends to me licking their testicles. But I don’t extend that assumption to their anus. I don’t like rimming people to start with, but even if I did, I wouldn’t assume that someone being okay with me licking their dick/balls means they are also okay with me licking their arse. There is no particular reason for me assuming that if a woman wants to have sex with me she’s okay with me touching her nipples, I just assume it because it’s culturally normal – there is no particular reason for me assuming that a man who wants to have sex with me doesn’t want me touching his anal region, I just assume it because it’s culturally normal. Actually, I have slept with a couple of women who’ve asked for their nipples not to be touched, and also with a couple of men who have asked for their anus to be touched. So the assumptions “if a woman consents to sex she consents to having her nipples touched” and “if a man consents to sex he doesn’t consent to having his anus touched” are, in my experience, false.
What’s the point of this ramble? Firstly, assumptions of what’s consented to when someone consents to sex are dictated by sexual culture, which - much surprise very wow - doesn’t match up with what each individual wants. Secondly, when I have sex with someone, I make assumptions about what they want and do not get consent for each individual act – and I bet you do that too.
More to the point, it’s functionally impossible to do this. Imagine if you genuinely did get full verbal consent for each action; sex would become impossible. Break it down – let’s say that for every part of the body you can lick, kiss or touch it, and that each part of the body is considered as its own section for consent-giving purposes. Imagine trying to kiss down someone’s neck to their breast if you got full verbal consent for each act:
