When you say lust enhances love do you mean lust for one another? I always listen very carefully when you speak, please explain?
There are many aspects to love and lust:
Being in lust/love, sometimes it's hard to tell the difference.
Lust, kickstarting fantasies and sex with the one you love.
Lusting after a different person can heighten sexual tension during sex, and for me at least, my fantasies end with my wife being my fantasy partner.
Lust brings excitement and sexual awareness that you are still a sexual person, brightens your day and stimulates your gonads, then you can bring it on home.
Whatever blows your skirt up or gets you juicy is all right with me as long as we love each other and you bring your lust home and share it with me.
