My ex said her best sex ever was with her ex-husband. They were great in bed together, but just couldn't live together. It wasn't a cock size thing at all, he just took good care of her in bed. Current wife of 30+ years has been very consistent as to which guys were her best lovers lovers over the years we've been together. Like all married couples, we've discussed this many times. Especially while we were having sex! 🙂
She rated two guys as current "bests" - one a white guy who worked for the same company she worked for. The other an African-American guy who also worked for the same employer as my wife. She had been seeing the black guy for a while, once a month, before she and I started dating. He was a monthly regular for at least a decade. His wife knew and once told my wife how grateful she was that her husband was having sex with my wife - "it gives me a night or a weekend off once in a while," she said. Things slowed down as we all got older but my wife really enjoyed her time with this man. He loved to take her to dinner in nice restaurants and show her off to his friends. They'd meet in her hotel room when she worked in his region and quite often he'd spend the night. He wasn't the quintessential hugely hung black guy, although (according to my wife) he was longer and thicker than me. She guessed he was seven or eight inches but it was the thickness that really got her off. I was never with them although once she left her cellphone open and I was able to listen and stroke myself to orgasm.
Her white lover (of about four years) was also married and very good in bed. His wife had health issues and did not engage in sex with him, so he was horny as hell all the time. He was a frequent guest in our home in our marital bed whilst I slept elsewhere. The first time it happened it was in our home in our guest bedroom after a party and I peeked in through the door. I couldn't see them as they were covered up, but he was on top of her kissing her and the sounds of my wife having an orgasm and the aroma in the room told me what was happening. I backed away with a raging hard-on. Later that night, she visited me in our marital bed and gave me seconds, then returned to him for the rest of the night. Her period was way late after this "session" and we experience the angst of thinking she was PG and could we go through with it, - what to do (if anything)? There was some heavy emotions between my wife and this guy, - such that they had to take a break at one point in order to keep his marriage intact. My wife and this guy worked together on out-of-town projects from time to time, resulting in long hotel stays in hotels designed for longer term stays. This man checked all of her boxes and it was by mutual consent that they broke off the relationship due to emotions running out of control. I guess it's one of the downsides of a lifestyle like this, - the end can be tearful for all involved. He too was nicely hung (according to my wife - I was never in bed with them), about the same length as me but thicker, she said. "I just feel so warm and sexy when he's inside me," she said. We are still friends with him, but have gone our separate ways as we have grown older.
On more than one occasion my wife reminded me that while I was "a good lay" for her, I wasn't in the same league as these two guys. That's where it stands today.
