I had protected sex about a week ago. About 6 days ago, Wednesday I started to get itchy around my body in my scrotum area and anus area. It usually itches at night while I'm in bed. I started to get small bumps like bug bites or mosquito bites on my thigh n stomach and chest. After applying alcohol the next day they're usually gone or are really small. Friday night I felt an itch around my scrotum so I woke n applied alcohol, I started to examine it and found a small red bump on it. It doesn't really look like a blister. I'm not really sure if the itch is coming from it, but other parts of my scrotum still itch. It's been three days since i last found it and nothing has changed, it still looks the same. At night I apply alcohol to my scrotum and it stops itching. Also my penis tip itches sometimes after I urinate, but I have history of fungal infection, jock itch on my penis tip because my forskin doesn't pull back. Should I be worried? I'm gonna go get check this Monday by a doctor to see what it is.
