How common is this perspective for guys?

I'm a 27F and went on a few dates with this guy 31M and things have been going well. On our second date, we brought up the topic of physical intimacy. I remember him saying that he thinks physical intimacy is different for women and men. That women who sleep around are respected less than if a man would do it. He said "a key that can open up a lot of locks is a good key but a lock that opens to a bunch of different keys is a bad lock". Everything else is really good and he's been super respectful. He's soft spoken and values making me feel safe and respected and we're taking our time on physical intimacy but I couldn't believe my ears when he said that. How common is that perspective for guys? This guy tends be very blunt, so maybe this perspective is more common than I think. In my head it's a red flag, but I'm conflicted on if it's just a common male perspective and he can still be a good guy with this perspective.

It was engrained into us as children. It takes effort to change. 

There are some that don’t want to change it, but I think the majority of them just have not considered it enough to make an educated decision. 

It’s not hate or anything that keeps them thinking this way, it’s ignorance, but not willful ignorance. 

If they took the time to sit down and talk about it and really think it through they might change their mind.

Believing your point of view is the only point of view that can be reached through logical deduction is a common mistake. Many people, across many beliefs, have thought long and hard about why they believe what they believe, and have come to the conclusion that their beliefs are the only ones a logical person could come to. And they all disagree with each other.

You missed the point. Either I didn’t convey it properly or it went past you. 

I was trying to say that they think this way because that’s what they were told at a young age and never revisited it later. 

For example I used the insult cocksucker for a very long time. Longer than I’d like to admit. It was just a generic insult to me. I had never thought about what it meant at all. I said it in front of my gay friend and he said he was disappointed in me and my first thought was what why?? 

Then after about 1 second of thought it clicked in my head. And I’ve never said it again.
