Umm no. Sexual intimacy strengthens marriage even in old age. Conservative and religious women absolutely love sex and want more in their marriage. One reason why there is so much divorce...lack of intimacy in marriage. Much of it by men who stopped getting physical with their wives and ignore them.
Every survey of women of all ages is they want more passion and intimacy in their marriage.
You tell prospective women about your views and they will run like the wind...and that is why I suspect you are still single at age 50.
Well, any really conservative woman loves a man that lets go of his own pleasures for more of the spiritual love. One displaces the other if we are moving towards God. That is just a fact.
