I have a few different areas on my penis where its pink in color, thin and irritated. The same spots show up every time I masturbate. It all started a few months back when I masturbated with some of my wifes lotion. I use different lubricants all the time. Mainly lotions and shampoos or conditioners. When it happend the first time, it made it real raw and bleed a little. I let it heal up and when I went to masturbate again, using a different lotion, it did it again. It's been doing it all the time now. I've been with my wife for 6 years now and gave been faithful. So I don't think its an std, unless u can get one from your penis hitting a public toilet seat. Done that a few times. That always freaks me out. Can anyone help me. Little worried here.
