I've been concerned about this in the past. I actually did a post some weeks ago asking if some brothers felt used sometimes, but it got no response.
We always met our friend B in a social setting and chatted and got to know each other before anything happened. My wife really didn't care how big his dick was, she really LIKED him, as did I. Of course, there was no "bull", "cuck" or any of that stuff either, just a white wife that wanted it, a black guy that wanted it, and a husband that wanted to see it. simple. Always when we met up after that, maybe 4 times a year for about 4 years, we ALWAYS took about an hour to grab a bite, a ******* or two, and catch up with families and careers. Then of course, they had sex, but it didn't feel cheap. In our opinion, and this is just ours alone, this is why a hit and run doesn't work for us. If there is a friendship, coupled with a desire on their part, everything is SO much better, and no one, him or her, feels like a piece of meat.
again, not trying to impose our will on anyone, just our experience.
