tiny red bump on penis gland. Woke up last week monday with it. Sunday night i rubbed my penis on vagina during sex. It wasn’t lubricated and dry. When i woke up monday morning my penis was dirty with lint and hair on it. As i cleaned it off i realized the small red bump. Before that i havent had anything like that and always use a condom when i would have sex. A day or 2 after it showed i tried to scratch it and my skin was scraped because of it. Dont know if it would make it heal longer or not. I’ve read online that it could be due to friction and poor hygiene. My workplace is outdoors so i sweat and dont get home to shower till 8-9 pm. I am also uncircumcised. I dont have any itch or pain and can also urinate normally. Please help
