Joe JonasWhile he was a teen idol with tons of lady fans before he hit his 20s, Joe Jonas lost his virginity at 20. He explained, " I did other stuff before then, but I was sexually active at 20. I’m glad I waited for the right person, because you look back and you go, ‘That girl was batshit crazy. I’m glad I didn’t go there.’" LOLz! With all the high profile affairs he had, we can only imagine who he's referring to as cray cray!!!
