I am a 19 year old make and for about a year ago, I began experiencing painful rubbing of my penis against the fly of my boxers. I had since tried countless types of underwear, but nothing seems to give me back full comfort. Recently, I have tried wearing size small (I had been using medium) boxer briefs made from a polyester nylon blend. Cotton had rubbed horribly, so I am now on to synthetic materials. These underwear felt really good for a while and I even ran a little which I had not done outside for some time. However, that night the bottom of my shaft was red and irritated. It seems no underwear works for me.
Does anyone have any advice on types of underwear that could help get me back to full mobility?
Thanks.
