Can you know someone had oral sex by their smell?

[YellowPamonha]

Hello. I'd like to know if, after oral sex, other people can know what you did because it leaves some specifc smell. If I were to give my boyfriend a handjob and he came into my mouth, would anyone be able to smell anything, considering I would wash my hands with water and soap and brush my teeth after? We have a couple of hours alone max, and while it is something we both have wanted to do for a while, I'm afraid his parents or mine will suspect what happened.

Hi YellowPamonha,

Nope, there is not a specific smell that oral sex leaves in the mouth that another person could use to "prove" that's what they'd been doing (too, if you use a condom, there's no fluids passing into your mouth to leave a smell, period). Not to mention that if you brush your teeth after, all anyone is likely to notice, if they notice it at all, is the smell of the toothpaste.
