...I had what would be considered a very low risk or no risk encounter (quick manual stimulation), but I'm a bit of a hypochondriac and anxious person. I'm wondering if after 4 weeks with no symptoms I can consider myself most likely free from disease. Of course, I realize some people are asymptomatic, and HPV may take many months to develop. But generally, after 1 month and no symptoms, can one consider oneself safe? Thanks for all you do on this website -- it's one of the few honest and informative websites about STDs. All the best.
