Maybe it's because you have never washed it so much before?? An allergic reaction to soap or shower gel
Definitely another possibility, if you showered 3 or 4 times that day, washing your cock each time, you might be a bit dried out. You shouldn't really put shower gel on the glans, let alone near the pee-hole, the irritation can leave you susceptible to urethritis.
OK, Admin is letting this one run now there is no specific allegation against any provider.
As for Charlie Sheen, he was reportedly was an intravenous drug-user...in a drugged-up stupor a shared needle was likely the means of transmission of his HIV infection...and who knows what other risky behaviour he indulged in when high and spending his cash on pornstars...was he barebacking them??
Rubber up for penetration and you eliminate nearly all risk of HIV infection...and obviously don't have fluid contact with strangers if you have an open wound/broken skin.
