Here's a question for everyone. I had sex with a guy I met online about 5 weeks ago. He was a large guy and wore a large condom. I bottomed and he came inside of me (I could feel his cock pulsing). I was on my belly at the time and he just laid on top of me instead of immediately pulling out. When he did I rolled over to wank and saw him get up and walk to the bathroom and I heard the toilet flush. I usually like seeing the full condom but didn't this time. I had no feeling that there was a breakage - I guess he would have said something but he said nothing - plus I didn't have any leakage or feel any cum (just lots of lube). I went to the toilet and sort of pushed but nothing came out.
Anyway, 5 weeks later, I'm feeling run down, flu-like symptoms, yucky etc. Coincidental?
