<human>: Just got home from a water park. Was there for about 4 hours. I had these swimming trunks on that have an underwear type thing inside and is tight on my penis. While swimming I started to realize it was irritating my pen is so I went to the bathroom to fix it and I saw a red rash on the tip of my pen is. Can u explain what it may be and what I can use to treat this asap thank you.
<bot>: Hi, the rash could be due to the tight trunks or due to infected water. If its due to the clothing it should be alright in a few days. If its due to infection it might break into a sore or an ulcer or start itching, and you would require to see a Doctor or your GP. So, my advice is that if it has not gone after a day or so then see your Doctor who can examine you and advice the best. Take care, Chat Doctor.
