Good thing it's looking more and more like that 20-year-old woman's baby-daddy claim against L.A.'s own underage heartthrob Justin Bieber is a crock.

Turns out that teen boys who have sex at a younger age could end up with, well, smaller parts. Yeah, and you thought that guy in high school with the peach fuzz mustache who dated all the cheerleaders was so cool.

Turns out he might have smaller junk than Barry Bonds. Ohio State University research suggests, according to the school, that these high scorers could end up suffering from …

… smaller total body mass as well as a decrease in accessory reproductive tissue, including the seminal vesicles, vas deferens and epididymis, as adults.

Bummer. So everything in life that's supposed to make you manlier — steroids, high school sex, reading GQ — actually has the opposite effect?

Read 'em and weep, kids.

Well, there is some hope. The Ohio State University study, released this week at the annual meeting of the Society for Neuroscience, used hamsters, not Biebers:

They found that these male animals with an early-life sexual experience later showed more signs of depressive-like behaviors as well as lower body mass, smaller reproductive tissues and changes to cells in the brain than did hamsters that were first exposed to sex later in life or to no sex at all.

It's possible that boy junk reacts differently to early access. We hope.

Anyway, Bieber's still a virgin, right?
