This was an interesting thing for me to read considering my mindset today. I'm at a stage in my marriage where I do feel some sexua| frustration and repression. It sucks when the passion subsides because my libido has not!
I love sex, always have and it's always been important to me. I guess this would be hard to understand if this is not the same for you. It's not quite as simple as "getting over it".
Still, there's more to this philosophically. I would never cheat on my husband. There is so much I get from our relationship, it would be idiotic to risk that. What I do think is that learning to deny ourselves in lieu of a higher purpose is a great principle of spiritual development. This is why Ghandi choose to restrict pleasures, not just sexua| but food as well. Idle pleasure seeking is short sighted.
I'm rewarded every day by the emotional bond that I share in my marriage. And occasionally, I get a little passion as well.
