Way back when I was young, my first 2 wives both took birth control (pill), but still let men come in their pussy when they took other lovers. I wasn't required to wear a condom, and we would still fuck and I also came in their pussy. Now, occasional denial happened, and their lovers had priority over me, but (the lack of) frequency for me was the 'penalty' I paid.
No kids from first marriage, but did have one with the second. Her being pregnant was a total surprise or me; as I mentioned she had been taking birth control, and we hadn't discussed her getting pregnant. She was VERY active outside the marriage, and I can't swear I'm the father.
Since my middle 30's, every woman I've been with, including my current wife, has had hysterectomy or tubes tied, so there was no pregnancy risk, obviously. The benefit of that was everybody they were with could cum in her pussy as much as they (or she) wanted. Again, a condom was never required for me, and I could still cum in their pussy.
But, as my wife has aged, denial became a real thing, and is total now. I haven't had her pussy in years (likely 3 or 4 at the least). She's not giving it up to anybody else, either. She would have fun with a coworker on occasion when I would be away from home for an extended period, but it's been even longer since she has done that.
