NFL Draft Shocker -- Cyber-Porn Traffic Goes Flaccid ... During Dramatic 1st Round

While Johnny Manziel’s draft day saga was a ratings boom for ESPN -- with a reported 50% jump in ratings from last year -- it seems to have hit the porn biz right in the trousers.

Sources over at PornHub, one of the top naughty sites on the net (so we hear) tell TMZ Sports that traffic on their site was DOWN nearly 15% Thursday night -- the 1st round of the NFL Draft -- with the horny young men of America choosing to watch Johnny sweat in New York, rather than watch fatherless young women sweat in the Valley.

Smut lovers shouldn’t be discouraged though, because PornHub tells us the X-fans were back in front of their screens the next day and traffic was THROUGH THE ROOF, topping 40 MILLION viewers.
