I agree to a point; however, having shared my wife with both strangers/those we met online, and also several friends/acquaintances, I can tell you that in all but one case the friends came more quickly. With strangers/online "hookups" there isn't that familiarity and connection that you have when friends are involved.
Every friend I've shared her with knew her/us at least a couple years prior (and in a couple cases, much longer than that) so there's that playful flirting and playful sexual tension that builds up over time. And the friends will inevitably admit (after "the deed" has gone down) to having jerked off thinking about fucking her. They just never thought they'd actually get the chance. So, when they actually do get the chance, with my approval, the "taboo" of it and that tension that has built up typically results in them shooting a lot more quickly. One friend in particular actually came within a couple minutes of her sucking his dick. Of course, he recovered quickly and his stamina was great after that.
Anyway, I guess I'm just saying that all situations are different. My wife prefers friends/acquaintances over strangers for the exact reasons I mentioned above, and I do as well. She views them cumming quickly the first time or two as very hot, and a major compliment.
