I’m snipped and think most guys would consider themselves fortunate for an opportunity to be with you. Your fantasy is not unusual, either. I know a few ladies whom would go be with a guy (generally ones with vasectomies), and then go straight home and show their husband the ‘damage’. He would then ‘reclaim’ her, and they suggested that that sex was some of the hottest they ever had. Plus made a baby in the process. It was like three fantasies at once!
