I wiped my anus with toilet paper that contained fresh semen from an infected person with an std. can that transmit the std to me?

Exceedingly unlikely, but if you know for sure the semen was from someone with known infection there might be a slight chance and might want to be tested. Better safe than sorry. (Since it seems you're probably a man who has sex with other men, you need periodic STD testing anyway. Maybe this is a good time, while it's on your mind -- even though the risk is nearly zero.)

There are many types of stds and in this scenario the chances of you getting one are extremely low to 0
