Well, you can be telling a story to your bud, and say, if you were on vacation... long story short. and then we had wild sex. If your man never told a story like that to a bud, well... he ain't prolly very manly.
Not true. I know some very, extremely, completely, totally "manly" men who don't kiss(or whatever) and tell. They think it's no one elses' business. And they're right.
It's kind of like some of the guys I met who competed in the rodeo. Some weekend warriors bragged to every girl they'd meet, had the biggest, shiniest buckles, etc. Then there were the quietly confident ones that didn't make a big noise, wore a trophy buckle that wasn't all shiny, but they earned it.
If you have to tell people who you are and what you think you've done - you ain't all that. If you can make the ride - other people know who you are already and they know what you've done.
