I can't answer the question but it would not surprise me if they do. During gestation, as a babies' sex is being determined, the brain is bathed in different chemicals (hormones and such) depending upon the sex. There is a lot of clinical evidence that male brains are simply wired differently than female brains. Certainly, there are a lot of similarities but it wouldn't surprise me if these differences in wiring change the perception and experience of love.
The problem is that emotions and the experience of them are inherently hard to communicate to others. We speak in commonly used terms of love, adoration, loneliness, sadness to convey how we feel but do those words actually convey how we feel. It's like explaining colors to a person blind from birth. How can we really explain how we feel, how we love to another person and know with certainty they understand? This isn't even delving into the issue of men and women experiencing love differently as a result of social and cultural training during their upbringing.
I think in the long run, this is an unanswerable question but it certainly is a great question that, no doubt, would spark some great debate!
