Bleeding nipples.

Have any of you baws experienced more frequent bleeding from your nipples as you get older? I’ve been running long distances off and on for the last 20 years.

My first experience came after about 10 years of running. It was a 10 mile run on a hotel treadmill and I wasn’t wearing a form fitting shirt, so the fabric was basically rubbing against my nipples every stride. I didn’t feel any pain during the run, but afterwards I looked into the mirror and noticed two red streaks down my shirt. Eventually I realized the streaks could only be explained by blood from my nipples.

I wasn't at all concerned with the first occurrence, since I was on a treadmill for 10 miles wearing a shirt that could easily explain the situation.

For the previous 10 years, I haven’t had a similar experience. But in the last year I’ve experienced similar red streaks down my shirt twice after 7-8 mile runs. Both of these times I was wearing form fitting shirts where the fabric shouldn’t have been rubbing across my nipples as much as the first time.

Have any of y’all experienced this? I don’t have man boobs. But as you get older, do your nipples change and make them more likely to bleed when you run more than 6 miles? It doesn’t seem to cause any pain or other issues, except two red streaks on my shirt beginning at my nipples.

What do you recommend? Should I make an appointment with a boob doctor? I don't think I need to change shirts, since this style has worked fantastic for 19 out of the last 20 years. Should I just keep running, and then proudly walk around with nipple blood streaks on my shirt, as I have been doing?
