Can you please list all the STDs you can get from a toilet seat?

Thanks so much.

None.

Unless the person with the STD just now used the toilet and left a wet spot containing an STD on it and you put a part of your body with an open sore directly over the wet spot and stayed directly over it for a few seconds.

STDs die almost immediately when exposed to air. They live longer near the genitals because they are wet and moist.

Don't sit on a wet toilet seat and you will be OK.

I thought you could at least get crabs, because they walk around on it, correct? I always take tissue and wipe the seat before using, just in case anything is crawling around.

Crabs do not just walk around. They jump from one live being to another. Wiping off a toilet seat is always a good idea - but it isn't going to help or hurt you get a STD.
