### input:
I have made a habit of masturbating at night for a good amount of time. I am uncircumcised, but i still sometimes use lotion for an added sensation. I have always wiped myself completely clean of any and all lotion after masturbating with it, as well as semen. I even pull back the foreskin and fairly roughly wipe off the glans and parts of the head that are usually unexposed. I have been doing this for years, and before recently, haven t had any problem with it. I am also a virgin and haven t had sexual contact with a girl in over six months, so an STD is not an option. I have been masturbating with lotion for about a week now that I m home. Two nights ago, however, I woke up in the middle of the night to a severe itch on the underside of my penis and scrotum. I couldn t sleep, so I scratched it until I was comfortable again. I woke up to slightly reddened skin on the underside of my penis and scrotum. The itch went away during most of the day, but at night, again, I masturbated (this time without lotion). Yesterday, I woke up to slightly more irritated skin, becoming more red and becoming slightly swollen around the scrotum and foreskin. Now, my penis and scrotum are very red and irritated, and my foreskin is very swollen. It is also slightly painful. I have been reading a lot about yeast infections, and it seems like that is the probable cause of this. I don t know how, since I have been cleaning myself with the same routine for years and I haven t had any trouble until now, but nevertheless, it seems like the logical decision. However, what deters me from thinking this is that the day before I started noticing the itchy penis and scrotum, I was out in the woods doing yard work, and it is very probable that I rubbed up on either poison ivy, oak, or sumac. I think this because even though my genitalia was the first area to become itchy, and is at this point still the worst, I have been developing rashes on other parts of my body. Is it possible that I touched my penis before adequately washing my hands and the poisonous oils from the plant spread that way? Or is this just a side effect of a yeast infection? Is it a possible solution to just wait this out, or should I seek medical attention?
