Hi, I'm 19.l And Last Year I I Used To

Hi, I'm 19.l and last year i I used to dry hump a rug in my bathroom without underwear on. I'm very ashamed and embarrassed by this since i knew people stood barefoot on it, but can I get any kind of dangerous infection from this? Whenever I did it, I always showered afterwards and washed in that area well to clean it. Thank you.
