I can jerk off without lube because I’ll start to precum a lot after a bit, and if I edge I’ll eventually start having small oragasms where I dribble or squirt some cum each time. This gets really sticky as it dries, and then wet and frothy again if I spit on it or when I precum and cum some more. My balls bounce around like crazy when it’s not as wet because I glide the skin up and down my shaft until I’m wet again, which feels pretty good.
However, when I use lube, I prefer silicone or coconut oil because it stays wet and mixes with my fluids nicely, so I slather it all over my cock and balls before I start. Because it stays really wet, everything is much more sensitive, so I precum much more and have many more of those small orgasms, which makes a huge mess by the time I’m done.
All this gets me extremely hard and throbbing at its maximum size. I think this happens because I use lube when I fuck and a good mouth is always wet, so my body responds more to those sensations.
It’s annoying to clean up when I use lube, and I always sit on a towel so I don’t get whatever I’m sitting on soaked with my juices, but the pleasure is absolutely worth it.
