Yea, youre probebly right about being minors although being a minor in this time of age doesn't guarentee not having sex yet at all though . But still, the one piece suit is a training and fighting outfit. So i guess all the athletes out there that wear tight outfits like the bike races, the sprinters, etc.. They are all really gay right?
Untill i see Sasuke flirting with guys he will be hetero in my eyes , and probeble in kishimoto's eyes as well . And hes the only one that really knows since hes the creator. Especialy since he had to train to increase his speed dramaticly , it just makes sense.
