Hi this is a wierd one but I've noticed a week after intercourse that I've had a really painful red sore its hard to explain the place it's like the outskirts of my lip downstairs. Im panicking hoping it's a general sore but it looks like a red lump ish sore and it has like maybe a tiny bit of fluid inside like a fluid spot i took pic this morning with flash to see what it resembles so i could get a good idea of how to explain. Now the weird thing is this encounter i had i had been talking to him a few months on and off and he wasn't on the best place living wise homeless etc. Now I also got talking to the brother nothing like that just normal chat now he's told me have i been checked out because his brother and his mates kind pf wound me up joking maybe saying you want to get checked out. Now what worried me as he's lost his phone now i haven't even spoken to the guy but his brother is on holiday with him i rang the brother last night he said did u get checked out is this a indicator of something like he knoes something. And i only had this encounter last Friday would symtoms show this soon?
