Your wife sounds like mine. She can't get pregnant and our preference is long-term bf's, for her. She knows I like denial, so I have gone well over a year without having sex with my wife, while she's having regular sex with her bf.She prefers it bare and for them to cum in her. She cant get pregnant so its all good there. We rarely have sex and i havnt cum in her this year yet. But i think it would be hot if i had to ise a condom when we did have sex.
My wife likes young, large, muscular guys. We are in our 50's and my wife's current bf is a young, well hung, 6'2" muscular 30 yr old guy. At his young age, he's already divorced and very sour on marriage. Plus, he likes older women. Not just because he finds them attractive (kind of a school boy/teacher thing) but because they bring less drama and lower inhibitions. So, he really likes the arrangement he has with me and my wife.
