I accidentally touched my dads friends crotch area and he didn’t react?

He’s probably between 50 and 60. I was helping him put together something and we were crouched down. When I spun around to get something my hand landed in his crotch area like stroking it/ back of hand pressing into it. I felt something in there like a cushion so it wasn’t hard. I’m 27 and he’s 50. Would a 50 year old notice or care if a 27 year old did this to him? At 60 would he also? I’m just curious about how men think changes as they age thanks. (Please don’t judge but i was turned on by it but he didn’t have a reaction.)
