Nipple issue

Go to your local running store or online.  They have stick on pads that prevent chapping for men these may help you hide them and they are not noticable under clothing

 Sorry and we do hear your concern, but personally I have always enjoyed a women's nippleitus, so maybe they enjoy ours.

Now for the serious comment. The runningnstore is a great place to pick up chaffing covers, this will probably handle the situation nicely.

Most tribes consider hard nipples sign of a warrior... but if your gonna cover them Id rock the neon booby tassles

Andy Bernard, from The Office, just flashed into my head.  Thanks for that. I would suggest a tight undershirt with the polo shirt.
