See, I’m not crazy! I’ve thought this too. Like, ok, sure, I’m not going to get an STD if my dick touches the seat because those are some very specific pathogens, but we know there are others well-equipped to survive. Relatedly, I’ve also gotten more acne than usual after I visit a sauna and rest my back against the wall. That shit is dirty, and I’m almost sure it makes me break out.
