This is a really interesting topic especially because I always thought that guys have it harder in the relationship department. As a woman you may have to adapt to certain standards of beauty, but at least as a girl I do not need to work up the courage to actively hit on a guy. It's just socially expected of men to do it while girls are on the receiving end of the deal.
But I guess I would hve a hard time doing that with or without ichthyose, after all rejection hurts regardless of the reason you are being rejected for
Before college (I'm currently 20 years old and have CIE, just some basic information), I went to an all girls school and I think that helped me alot in the 'bullying' department. Girls can be mean, but without boys we also tend to form closer bonds. I really feel that it took some of the pressure of my teenager years that I didn't need to deal with boys and realtionships on top of the issues of growing up and having ichthyose. but I guess it also sheltered me in the sense that I really do not have an exact idea what men go thorugh in puberty (I only see the result.......or you know, what counts as result :P)
