Can someone help me understand why some men make sexual comments regarding women to each other, in the presence of other women, but seem to think that it's an inside joke that the women won't get?

For example, once I was out with my boyfriend and his friend and wife whom we only saw a few times because they lived a couple hundred miles away. We went to Red Lobster. My boyfriend’s friend ordered lobster. When his food came he went through a whole lot of steps to get it just the way he wanted it. He added things, he smashed it up. It took him about five minutes! Which is fine, but at one point he looked at my boyfriend and said, “Half the fun is gettin’ it ready, ain’t that right Jer!” (insert manly, knowing smile here.)

Another time my husband and I were camping with his friend and wife. I was making bacon over the campfire and after it was all cooked my husband’s friend complained that he preferred his rare (well why didn’t you tell me that before, ding dong!) Looking at Rick, (again insert manly smirk,) he says, “We like a little wiggle in our bacon, ain’t that right Steve!” (In both instances my men kind of smiled uncomfortably and apologized to me later for their friend’s behavior. Which I appreciated.)

It’s disrespectful and low class in my opinion, but somehow they honestly seem to think we women aren’t going to “get it.”
