"I think it can also be the young ladies that are looking for a little bit of notice: 'Oh, I'm being taken out by a certain great rugby league player' or whatever — I think that's wrong. I think that's wrong."
His statement went down like a lead balloon on social media with the masses quick to slam the former player.
Mortimer said he was shown one of the tapes and couldn't believe what he was seeing. He said video was "embarrassing" and "should never be shown that way".
"Today I went and saw a bloke that I absolutely respect in the game of rugby league, and won't say who he is, but he showed me this on his iPhone and I just could not believe it that they were having sex," he said.
"I just thought, how embarrassing is that to yourself and it should never be done. Should never be shown that way.
"I don't know what the answer is to fix it up but I do know that we can – all clubs can do with a lot more ambassadors to settle the players down."
Mortimer's words come as the league continues to battle the ongoing sex tape scandals that have painted the NRL in an ugly light.
The Penrith Panthers came out swinging in defence of their culture amid the NRL sex tape scandal which has resulted in Tyrone May being charged and stood down.
Just 10 days out from their season opener, the Panthers are a club under siege after the release of four sex tapes over the past week involving three players.
The NRL stood May down indefinitely after he was charged with two counts of recording intimate image without consent, and two counts of disseminate image without consent.
On Thursday, a legal challenge by Jack de Belin was held over in the Federal Court because the NRL had not yet drafted its "no fault" stand down rules.
Effectively, it means de Belin and May are not suspended — however that will change when the NRL signs off on the rules, which is expected to happen in the next 48 hours.
