HI, I have participated in sex with my girlfriend when she was in her periods. I did it for 2 days and then from the 3rd day i started having discomfort inside my penis and this is the first time i am experiencing, and to be frank I didnot use a condom, ofcourse I never do it with my girl friend. I dont have any burning sensation but I can see at the opening of my penis head from where i urinate and ejaculate have turned little more read and when i press the bottom of the penis shaft i can feel some senses at the tip like little pain and itchy...sometime even the same feeling passes through the tube through which my sperm travels out. for 2 days I can feel the odour of her blood, because i had sex for very long time staying inside her for almost 1 hr. and i dont have any discharge but i only have a little pain in the tip of my penis head and its not going off. when is try to masturbate i feel better and when i press my penis i feel the itchy sensation I am worried, as i infected or is it a normal thing. If I am infected is it very serious and what is the way to over come this and become normal. Please help me out with this situation and suggest me something.
