Do bottoms ever need to poop? Is that just not an option for bottoms?
Actually I've seen a few. Some genres even commit to uncensored showing of it. Its hella gross. But I've read some that clean out, some that bleed, some that poop, and those that use condoms. I've only read one where they did an aids test before and that was sweet for me. But I get what you mean, those ate uncommon.
