hope i don't have anything, need some help

[gripton]

So probably close to a year and a half ago I ended up having a threesome with these two really hot girls that were unfortunately kind of known for sleeping around. So as I said It's been almost a year and a half since then and I have shown no physical signs of having anything. Can someone tell me if there is any chance of me having anything and not knowing about it even at this late point?

Yes, there is a chance. Some STDs remain silent in one partner or the other for a while. You are probably clean but I would get checked after an interaction such as you describe.
