how can two people who love eachother engage in threesomes and orgies?

Sometimes I wonder about that too. But honestly according to research it's proven that both of them have similar interests and that's what makes them be engaged in these acts

There are quite a few possible ways. If the third person is a guy, you can try husband on top, wife in the middle, other guy on the bottom. Or, husband on top, other guy in the middle, wife on bottom. Or other guy on top, husband in the middle, wife on bottom...

...i think you get the idea. I will stop there.

Personally, I'm not interested in sharing my wife, but it's none of my business as long as you and your wife are both cool with it. Don't pressure her to do anything she doesn't 100 percent want to do, or she will resent you for the rest of your lives. Even worse is if you pressure her, she agrees, then you hold it against her that went through with it. Of course the reverse is true too.
