it's a good question, I always thought STDs were more infectious just because their direct route of transmission into the body with the large mucous bodies that are involved. Thinking about that recent term that's come up in COVID with viral load, it seems like with an STD you're opening the doors to a direct viral/bacterial load punch unlike the diffuse air transmission routes that drop like a mold spore and have to reproduce. I'm curious now when it comes to STDs is there any way to quantify just how much concentration/load shows up in body fluids and how potent the infectiousness would be for those fluids given that concentration. But now that I think about it, I'm curious which cavities in the body present the widest mucosal surface areas if you cut and open them up and measure them. The pharynx, the throat, the anus and colons, the urethra, the vagina cervix and uterus, how do each of those measure out. I've heard the colon is susceptible to infection because of the large network of lymphatic tissue just on the otherside and because it's designed to absorb stuff being the last mile of the digestive tract where traces of anything left behind at that final stage and still useful can be absorbed by the body. The application of suppositories come to mind in this space. Another angle might connect with the point brought up by the other individual about bacteria being a frequent origin of STDs, and bacteria generally share genetic material from what I understand. Maybe that bacteria to bacteria mingling is where the risk comes in?
