As a girl, I'd say it would depend entirely on your look. If you had a slightly rough, but stylish look, that would probably be sexy. The eyepatch has a massive amount of potential for hottness, so make sure you don't waste it! It really depends on who you are, what you look like, what would suit you.
I think a haircut that's at least not very very short would help a lot. If worn wrong, it could look really unattractive. If I was you, I'd play around with different styles and see what will look good, prefferably also have some women you know give advice.

Also, I'm very sorry about your poor eye.
