Very confused....

So the last guy I had sex with, about a week after we did everything unprotected, he come to me saying I should go get tested because he thinks I gave him something. I have no signs of anything, nothing smells, no abnormal discharge and nothing feels off or anything. I was only feeling small pains in my lower stomach for like 3 days and it all went away because I just started the pill back and I was expecting my period. Im 19 so I asked my mom to make me a Gyno appointment but she says it’s a 2 month wait or something since I am new.....So this entire time I am thinking he went and got tested and it came back positive as we all would think if someone is telling us this right? So I actually asked him after about a week of thinking, stressing and researching about this. He said he hasn’t went to go get tested, but he says the girl he had sex with two days after me is now burning when she pees and is feeling sick and this and that. I asked him why he thought I gave him something and he said he felt weird the day after we had our encounter. I asked him well what felt weird and this man had the audacity to tell me his testosterone felt off. That doesn’t even sound right. Once again I have no signs of anything and feel 100% fine and so does my vagina. I didn’t know what to make of this but hopefully someone can shine some light onto this situation.
