A few weeks ago was over at a friends place using the hot tub he has and his son was home from college and asked if I mind using the hot tub with me. Told him it was fine, but thought his dad would be back out soon. He pulled off his shirt and the kid i remembered with hairy chest was trimmed down pretty close. He got in the water and soon I saw a pair of trunks tossed over the edge. At some point after a while he got up out of the water and sat on the edge, he was trimmed and shaved there too. Asked him if that was a college thing for him to trim and he said it was partly and his gf liked the pubes trimmed up. Said he really enjoyed being trimmed up, he tried totally shaved a couple times and that was not for him. When his dad came out to join he gave his son some grief about the trimmed chest. He figured at least half of building he lived in trimmed/shaved somewhere on their body other than face.
