Compression Wear

We are supposed to wear compression shorts for rowing, but it is what we wear, no shorts above so that nothing falls into the path of the seat. When I wear something under the lines show. When I wear my balls do not show. I do not really care about my package, but showing my balls showing may be weird. What should I do? "

I tend to wear anything, but I sometimes get a rash, I go where thin leggings
