Massage Parlour

I'm probably being silly. If so, just tell me. On Saturday I went to Massage Parlour. I received a nude massage from a woman. She spent most of the first 20 or minutes stimulating and teasing my penis. She started giving me a hand job when I stopped her so I could massage her for a while. During my massage of her, I felt a dab of a sticky fluid on the towel she was laying on. I figured it was probably from me. I was leaking a little and I think they change the towels after every customer. The towel looked and felt clean when I arrived and I know she changed the towel as I was getting dressed to leave. But still I wonder: What if it was from the previous customer. I wiped that finger off on the towel. A little later I did touch my penis with that hand, but not the tip. My sense is that any fears I have are out of guilt and a little HIV phobia. Nothing else happened. And if it was from another customer, it had to be at least 3--40 minutes old. But more importantly, I wiped that finger off. I should let this go, shouldn't I? Sorry if this sounds farfetched.
