Blood is no more risky than contact with vaginal secretions, and some such contact like this always occurs even with correctly used condoms. This sexual event was completely safe and no STD testing is necessary. Don't worry about it.
Thanks for the reply. It gives me relief. I was worried because it was a one time thing with someone I didn't know, so I didn't know their STD status.
This is a separate thing... So, according to what you're saying vaginal secretions on the base of the shaft shouldn't pose an STD risk as well? (Just curious because some websites seem to indicate that vaginal fluids could be loaded with potential risk...)
The skin of the shaft of penis is no more susceptible to STDs than the skin anywhere on your body. Simple skin contact with fluids (or blood) is usually not sufficient for infection to occur.
Once again, thanks for taking the time to answer. I appreciate it.
if you have a open cut at the base of your shaft, you can get HIV. Any skin touching with fluids can give you STDs. ive seen warts at the base, scabbies, pubic lice, to name some! if its unfamiliar, becareful!
STDs aren't nearly as easily transmitted as the comments by NocOut suggest. And nobody has been reported to have caught HIV because of exposure of a "cut" on the base or shaft of the penis. For example, no known transmission because of shaving nicks. This is a theoretical risk that probably doesn't mean much in the real world.
