i wanted to protect my skin as well as my pride when i decided to buy PI knickers. they were about 55.00 and i just love them. they are very comfy and make me feel a bit less like the fat of my thighs are all over the place. i really like them a lot. shorts are just too much for me. ugh! so, my advice is get a pair of knickers. i can't imagine that shorts are much cooler in warm weather, and for me, it is worth it to save my self respect... good luck!
