The last time I was in Spain, there were three girls in our group. They kept getting harrassed by the Spanish blokes there. The men didn't seem to care whether or not these girls were available, interested, or just really scared, they carried on until we stepped in and pointed out that they weren't welcome.
I can well imagine it!
The only other European place I've been to where the situation seems worse is in Italy, where the men treat the women with so little respect it's actually quite disgusting at times.
