I've never experienced this before...and I think I will be unable to do this like Tulip. Personally, I reserve my heart for one person...someone who is absolutely special. I can only fall in love with someone with a very beautiful heart. So when I fall in love, I fall in love with that person and that person only.
Noticed that my personality is naturally monogamous. My relationships with people are very deep...even in love. I fall in love emotionally first and then physicality comes afterwards. I was even surprised that I could be so physically passionate---because I've never had that desire till now (after getting my first bf). So that physical need isn't so much the driving force (lust) behind things.
That special person is always on my mind...and that person only.
