Hi
I was curiouse so I had my first sexual experience with another male. We did not have oral sex but we masterbated each other and I gave anal sex without a condom (foolishly). Then the next morning we masterbated each other again but he was quite rough with my penis and as I have a very sensitive penis head it got quite painfull as he was rubbing it. I noticed that day that my penis head was red and sore and I got a burning sensation when passing urine. The redness and burning lasted till monday (the rough masterbation was on sunday) and was gone tuesday. Then last night (wednesday night) I masterbated for the first time since that encounter and it burned when I ejaculated. Now I start to burn when passing urine again and it burns afterwards but there is no redness.
Could this be a STI or a infection?
I am very worrid now.
Thanks
