Anyone who has any experience with one knows: Vaginas have liquid coming out of them. This is especially true if the owner of a vagina is having sex. Depending on the person, there will at least be some of the liquid coming out of the vagina at some point in the process. Some kind of absorbent padding will almost always be helpful in preventing stains. This is especially important if you think there will be some ejaculation, squirting, peeing, or period blood coming out at any point.
I made this mistake a long time ago when I fingered a woman on her period and got so much blood everywhere when she squirted that it soaked through the sheets and into the mattress, which required bleach to soak into it overnight.
Put something down to absorb it even if you don’t think anything will come out. Something might when you least expect it, so be ready for the flood.


Towels are great for sweat as well. It has usually, but not always, been my experience that ass and back sweat can ruin the smell of a room, and a towel is relatively easy to wash or discard.
We always keep a towel on hand for quick clean ups! We just don’t spread it out on the bed first.
We have three! A towel for our backs, two mini towels. We used to have warm water at the bedside, but I lost my water bottle and I keep forgetting to replace it.
That’s a good idea too! People discharge from EVERYWHERE!
Aside from squirting, which only some AFAB people can do, penis-havers produce a lot more fluids overall than vagina-havers.
Dicks do be blastin’
If it bothers you, you clean the sheets every few days if it bothers YOU.
You don’t passive-aggressively lay down a towel for your partner as a barrier to “protect your investment.” You take care of your shit and love the person you lay with or end it. There’s not much in between here.
This strikes me as insecurity leading into a defensive misunderstanding. Do you like the smell of your sweat or your partner’s sweat? Because neither of us are fans of the smell or the puddle, and I’ve only met one person who was. That could be the only way I could see this as even slightly disrespectful.
Edit: and I just realized, it’s my partner’s mattress.
