Do you have the time and energy to nurture a good relationship, or have you sometimes been so absorbed in your work that you neglected your marriage (or "informal" relationship)?
If you are living together, either in marriage or some informal arrangement, who makes more money; and how are the household chores divided? Many married men give lip service to the idea that they should do half the household chores, but they don't walk the walk.
Do you take care to not do anything inconsiderate? What are the things your lover/ partner did that made you feel loved? What are the things he/she did to make you feel demeaned or betrayed?
Which of the following are you?
What is the one statement about sexuality that nobody can disagree with?
Responsiveness is the most important thing.
Most men have had the experience of being with a woman who was like a rag doll. It wasn't much fun, was it?
My girlfriend, a long time ago, would sometimes hop on top of me when I was taking a nap on the couch and say, "Darling, I can never get bored doing this." But one time I was tired and didn't respond. She then got up and said, in a somewhat disappointed tone, "This is like making love to a statue."
In short, responsiveness is what makes sex fun. And this is true of everybody - man or woman, young or old, heterosexual or homosexual.
Isn't the same kind of responsiveness what makes another person fun to be with socially? Isn't it also what gets people emotionally attached to their pets? Or makes a toy fun to play with?
