I became the lover of a women 30 years ago in a strange way. My lover got married to a cuckold she found online. All of a sudden I was cuckolding a husband and did so for 25 years. I even attended the wedding and made out with her in an unoccupied room. Very weird day. I thought that would limit the amount of time she could spend with me but the opposite was true. She did not have to work anymore and her cuck took care of her son. She would spend weeks with me and her cuck even brought her to stay with me for a vacation once while he went off on his own.
She had considered a regular marriage and just having a occasional affairs but after hitting the clubs she said all the single men our age were single for a reason. She has two Master Degrees and a very dominant personality. For some reason a lot of men think that all women just want sex with a large penis and could care little about the man attached to it. I never met a woman like that but I am sure that they exist. She decided that finding a bull that she actually liked other than just for sex, was going to be difficult so she gave up on that idea and looked for a cuckold. There are no shortage of cuckolds looking for women online. 
When I asked my wife to have sex with another man so I could watch we could not find someone we did not know that was agreeable to my wife. My wife need to have an emotional bond on some level to enjoy sex. You are not going to find that with a bull or guy who is just in it for the sex. We ended up with the husband of a wife swapping couple we saw once a week. The guy was so rough with her that she had bruises when we got home. My wife was going to stop him but did not because he was a friend. He was all business just using my wife as a receptacle for his sperm. That was the end of her Bull finding days.
For the two women I loved, it was difficult to find a bull. I guess you have to be a certain type of woman who can have sex with no emotional involvement. Every married woman I had sex with got emotionally involved with me. Then again, I attracted those kind of women. Not as easy to find a guy who just wants sex as some posters make it seem. You do not walk into a club, pick out a man and presto, he has a big penis and is great in bed. Most men do not have big penises, even the black ones as anyone who shared a shower with their sports team will attest to. Not all guys are good lays or will perform as expected in bed. We were lucky that we kept it among us and that each of us fulfilled a need in the other. I feel sorry for couples who attempt this lifestyle for the first time. It is not as easy as they read online.
