We all seem to know that a healthy diet and working out, among other things, are vital if you want to enjoy good sex until the end of your lifetime. (Sorry for mentioning the word "end".) Suppose that you have just met someone. You have fallen in love with her or him, or you feel that a bonding relationship with them is really worth your while. But you were quick to discover that, although they are apparently ok, they don't have a very healthy lifestyle, conducive to (?) - leading to, I mean - fulfilling sex. They don't often eat well or work out. Do you think it would be appropriate for you, right at the beginning of your relationship, to ask them to or at least to suggest them choose a better lifestyle? Do you think it would sound preachy or pretentious to approach them with a few tips? Or saying, for example: "I want you to be totally well and healthy for you and me. I want to be making love with you for as long as possible. Please take care of yourself." Or whatever? Would it appear as if you were a control freak or telling them what they have to do? Does your current partner have about the same lifestyle as yourself? Is a convergence in lifestyle and healthy choices necessary to make a relationship bloom and last?
