Do you prefer woman's perfume or man's?

I have both man's and woman's. The photo below is one of my collection. and I use it occasionally partly because of its high price and partly because of its strong fragrance. But I love it because its fragrance is distinctive, very distinctive. I can recognize it as long as someone wearing the same perfume passes by me. I ran into two people in my working place wearing ezactly the same D&G perfume. One was a colleague returning back from the UK, the other was a young man! yes, a young guy. Surely he was a little womanlike.

It's acceptable if a woman wears man's perfume, but no way for a man using woman's, don't you agree?
