Can you get std from receiving unprotected handjob?

Unlikely, but...: A penis can catch an STD infection from a hand, if the hand has germs such as syphillis bacteria or herpes viruses. Those can be oozing through skin sores on the hand. The hand can also touch parts of her own body that are oozing gonorrhea, chlamydia, ureaplasma, or trichomonas germs... and then transfer the germs to the penis. That said, people should worry more about penis germs than hand germs.
