Re: ?'s about Cum
1. Sticky because of its ingredients (seminal fluid is very sugary, so it's sticky)
2. It can stain if you leave it on clothing/fabrics, but even then it can be washed off fairly easily (though it's very embarrasing if your parents see!).
3. It's liquid, so of course it's slippery (cuz....wet things are slippery). Though females produce lubricant for...lubrication, our cum can serve the same purpose (actually precum is meant to help lubricate the penis during sex).
