I was still worried and went to an old family doctor and explained that my proctologist, urologist, and my current doctor says not a wart and she also told me not to worry its not a wart.
It really is impossible to have online diagnosis.
But a good way to distinguish a wart is to see if the TEXTURE of it matches the overall surrounding skin. If you look at the "bump", see if the texture of it is different. If it is different, no matter how you stretch it, it shouldn't disappear.
Warts can't disappear by you stretching the skin.
But whether or not you have a wart, there is no way no one can give you a definitive answer here on the forums or online.
As for the handjob you got, that wouldn't give you a STD. You aren't at risk.
