Hi, I Usually Shave My Body And A Few Months

Hi, I usually shave my body and a few months ago a notice like a bump in between of my penis and my anus but I didn't do nothing because I thought I was a infected follicle but I shave myself today and I notice that the bump is still there. The bump is kind of red and looks like a cauliflower. What do you think Doctor it can be? I had the last year a girlfriend who had HPV and was treated.
