I have a feeling the mysterious goop was nair/hair removal cream, since it's known to burn on sensitive areas. Which makes OP's bf a huuge douche bag.

I never thought about that, it very well could be. Why her bf would do that to her is beyond me though, even if it was the kind meant for that area, without her permission it's a dick move. I feel even more sorry for OP if this is the case, that would hurt so bad.

I would vote some sort of lube before nair. I can't imagine him going "now don't touch it for a couple minutes. No trust me this is super sexy"

Believe it or not, some people are into hair removal as a sexual pleasure and for intimacy. Not my thing, but I guess whatever works for you. Doing it without discussing it with your partner is wrong though.

I get that. I just don't understand how someone could sneakily do it during sexy times. It has to sit for 2-4 minutes, what excuse could he use to have her sit still that long

Maybe he used icy hot?

That's what I was thinking.

liqued itch powder, othen used for pranks.

tiger balm maybe? or vicks vapor rub

I've never tried it, but I read that some women are a lot more sensitive to warming lube than others, and for them it really burns. I don't think the boyfriend would intentionally cockblock himself by using something painful on purpose.

Where does it say he had no remorse? We know very little of what happened so you shouldn't be too quick to judge.

I made an account just to give you a thumbs up

So, what do you prefer to call it? "Downstairs", vulva, slit, pussy, vajayjay, vag?

grow up, honey
