It's strong! For about as long as I can remember. At about 12 years of age I really got into it. I used to be a latch key kid and would get home hours before my parents. I'd kick off my shoes and walk around outside after a rain storm feeling the wetness under the soles of my feet. I'd look in my neighbor's driveway and make sure no one was home before I'd fine a spot in the yard where I'd cover myself in mud and just roll around in it! I discovered masturbation and orgasming playing in the mud! I had been having wetdreams for sometime, but did not really understand them. Then one day I was out humping and pressing my dick inside my pants as hard as I could into the soft mud! Suddenly I felt a strange urge! I felt like I needed to pee and I was ready to release it right there in all my glory, but then I felt as I could not control the release of pee, which ended up me having an orgasm in my pants! Damn!!!! It felt out of this world! Today at 46 years of age I still hump in the mud when ever I have a chance and relive that moment, though it will never be as good as the first time! I remember every chance I'd have a day off from school, or I'd play sick to stay home alone I'd play in the mud in the backyard. The drive to get wet and messy was so strong that even after showering off and putting on clean clothes as I was outside cleaning up and covering up my tracks I mad a little wet muddy puddle that I was going to cover up with loose dry dirt, but I couldn't resist - I went right back into the mud; clean clothes and all! Today, I still take days off from work without telling my wife to go play in the mud at my local park; however, it is getting quite hard as the rangers always repair muddy trails by building planks over the mud or filling it with gravel - fuck!! The best part about mud is that nothing compares to it, and it is free!!! I do love getting messy with food, but it is more mess to clean inside, and it costs. Hope to get back out in the mud soon, here in the San Francisco bay area! I don't think my wife will be into getting muddy so if there are any female partners that are up for a clean (non kinky) mud adventure hit me up!
