I Was At An Adult Book Store In A Booth.

I was at an adult book store in a booth. There was a fluid I touched, probably seamen, and I wiped it off mostly. I then wipped out my penis and put a condom on it before masturbating. I didn't touch my penis until after I had cum, and was squeezing out some remainder cum in the toilet. Is there any chance I might have picked up an STD or any other disease?
