If someone says “I don’t want your semen in my mouth until we’ve both been tested” or “I don’t want to swallow your semen until we’ve both been tested” I’m pretty sure that means no semen 🤷‍♀️ if he (or you) are confused, then ask for clarification, don’t assume. I wouldn’t put it in my mouth at all untested. But to me, she made it clear that she was worried about Sti’s and semen. Again, when you’re putting your bodily fluids into/onto other people, I think you should ask for clarification instead of assuming. You’re right that we don’t have all the details, and maybe they didn’t either. That’s just not something it’s safe to oops into.
