He was not interested in being poly because he was anticipated an imbalance in the extra-marital relationships that I'd get laid a bunch more, and he rarely would; which is maybe true since we live in a mid-sized, conservative town, and he can be shy. For as long as there are men who enjoy being fucked from behind and experience attraction to women, there are women who will happily oblige-and not just as a means of pleasing their partner, but also themselves. Afterward, wax poetic about how totally hot that was to play with her ass and you absolutely loved it. Because of our conflicting interests on this, we axed both possibilities and have just stayed I think happily monogamous. The only person I want playing with me…there…is you.
Some men actually have success this way! I have heard amazing stories of men who did just that and their women, after initial surprise, agreed to try it and ended up loving the feeling of fucking their husbands. This can be uncomfortable sometimes, even in decades-old relationships and marriages, especially if your love life has been closer to vanilla than any other flavor. His body is likely to become more resistant to penetration, no matter how badly his brain wants it.
