We used condom but my penis wasn't erect the whole time. When she was on top of me, she was rubbing her vagina trying to insert my penis in her but it wasn't fully erect, and when she got up, the condom stayed inside her. 7 days later i was drinking a cold drink and chips, then i felt something weird in my weird in my throat and wasn't able to speak for a bit. It has been hurting since then. Could it had been a lymph node perhaps from an STD? What are the chances of having contracted some type of STD?
