Regretfully, after a night of arguing with my girlfriend and drinking I had protected oral with a prostitute using a condom. When we finished, I took off the condom and proceeded to throw it away. I'm a little worried because the condom touched my boxers, of which I continued to wear until I got home a few hours later.
The oral was quite rough...I felt immediate pain afterwards. Two days later, I began checking the tip of my penis and it was a little red and somewhat rugged looking. Is there a chance it could just be bruised and I'm just being paranoid? I read somewhere that STDs/viruses don't have symptoms immediately like I did, which was literally seconds after. I checked on my penis head constantly so I'm hoping that is the reason for its redness/rugged looking appearance. I'm really worried that the outside of the condom which touched my boxers spread any STD to me.
Please help...I feel terrible. I have a girlfriend of 5 years that means the world to me. I've never done anything of this sort in my life. I know that I'm at fault and that this may be the price I have to pay. I don't want our relationship to end because of this and I feel so overwhelmed with guilt....please help!
