Hi Osman,
I personally find the Hijab very sexy and know a lot of other european guys that do too - I guess that's a little ironic given it's intended purpose!

I think it's because of:
1) It's a religious symbol, one that we aren't a part of - kind of the 'forbidden fruit' temptation I guess.
2) It brings the focus to a women's pretty face, accentuating her feminine charm
Fucking a pretty muslim women is one of my biggest fantasies. I do get to fuck a pretty Hindu lady though - my wife! And also share your fantasy of her fucking other guys. So far the progress is slow but we're definitely making progress, she now openly fantasies with me about fucking other guys and is much more sexual, she loves wearing sexy cloths and getting attention from other guys. If I had to sum up the driving force behind the change in her I would have to say that is all down to the changes in me. I spend much more attention to her - making her feel sexy and beautiful, buying nice cloths for her and telling her how beautiful she is. I've made sex about her pleasure, not mine. As a result she is more sexually liberated and confident in general. Patience is really a must, it will take a long time.
