I think there are different kinds of love (each love is different). I love my fiancee, mom, dad, and a few other people. I love beer too .

But the above is of course fooling around. Honestly, and now I answer your question, I couldn't love more than one woman equally. While I bet I could fall in 'love' easily but it would hurt my 'other' love. Not directly (but that too if she found out), yet indirectly - I could not love her in the same way.

True love is much more than desire, passion and attraction to the other person... It has to grow for a while and must undergo some testing in real, daily life... Yet, it is a different subject.

MY CONCLUSION
Maybe I am old fashioned but there can be only one exclusively in my heart :)
