An adult film star has revealed the one big mistake that men often make in the bedroom.
One of the world's most successful porn stars, Johnny Sins, has created hundreds of films and has millions of followers on social media.
Thanks to his experience in the adult industry, it's fair to say that Sins knows a thing or two about sex, and he offered up some advice to men about how to improve their love life in the bedroom.
Speaking to Daily Mail Australia, Sins also revealed the one question that men ask him the most, and it's all to do with penis size.

Sins said he is often asked by followers how they can increase their manhood, but he has a strict warning for anyone who asks.
"That's the number one question and unfortunately, besides some risky surgeries there's just no other way," he explained.

And it's not his only piece of advice, as he said that he thinks men should be thinking of their partners instead of focusing on themselves when having sex.
"I think guys are very selfish in the bedroom, a lot of guys these days are just trying to get themselves off and pleasure themselves rather than their partners," he said.
"And that's the exact opposite of what you should be doing."

Sins said he's always put his partners' needs first, explaining he would prioritise making a woman orgasm over 10 times before even thinking of himself.
"I've always wanted to please the girl I was with and make her orgasm 10, 20 times before I even think about it," he explained.

He revealed that for him, having sex is the part he 'really enjoys', which is why he prolongs it for as long as he can.
"Because by the time I orgasm it's over for the most part, and for me it's the sex that I really enjoy, so I like to prolong that as long as possible," he added. "My advice is to pay more attention to your partner and get them off as many times as you can."
Sins shot to fame online after working in the adult industry for 15 years.
Speaking to Vice a few years ago, he explained how it was some viral memes that led to his fame, rather than his porn work.
"I think it’s when the memes started coming out about all the jobs that I had. That was really the moment when I went from ‘porn performer, adult guy’ to sort of more ‘internet personality’," he said.
"A lot of people started recognising me and I got more popular just based on the memes and not necessarily on porn. It reached a whole new audience, basically, beyond the porn audience."
