I agree, why bother putting swimwear on just to get wet? You don't shower with clothes on so why do it for going in the pool? Boys should all swim naked.
I remember when I was living with my parents in Japan 40 years ago. I was 16 and discovered that the maids son who was 17 had the hots for me. Damn he was so much fun, I could fuck him and sure enough he would cum hands free. He took me to a bath house where gay frequently went, I was blond and green eyed and everyone wanted me. Those 8 months were important in my later life..
I know it's not Japan, but it reminds me of a spa in Singapore hidden from public entry where the young Asian men are so fucking hot and hard for old American fags.
