You analyze everything that happens during your love affairs. To you, having a lover is not so important as understanding the process of love. How it works, why two people are attracted to one another, what causes them to fall out of love – these are what interest you. On the one hand, this makes you something of a cold fish, someone with no true passions; on the other hand, your lover can expect some unique situations and experimental lovemaking as you use her for your ongoing research.
You are completely faithful to your one true love – until you find your next one a week or a month later. The classic romantic, you sweep your lovers off their feet, taking them to undreamed-of heights of ecstasy. Then you get bored and move on to greener pastures. You have no understanding of why former lovers should try to cling to you once the magic is gone. How boring!
You control every aspect of your relationship. No one else is allowed to take your love's attention away from you, nor will you tolerate flirtations with others. Your lover must be utterly consumed with you, obeying your every wish, working to please you at all times, and forfeiting his own desires in order to fulfill yours. In return, you focus every waking thought on your loved one.
You constantly test your lover, seeing how much he will suffer for you. You delight in pushing your partner to new thresholds of emotion and physical anguish. Not content with just whips and chains, you excel in mental cruelty as well. If he stays with you through it all, you know it's for real.
Love is a matter of trade-offs. You total up each expression of it, making certain that you get at least as much as you give (preferably more). Expensive presents, calls to one another, support during crises, paying for entertainment, number of orgasms – all these measures of your love affair must match up or the whole thing just isn't worth your time. You can't be bothered with those who are too self-centered to see to your needs.
