I think that we should all try to remember that there is a lot more to us that pcos, I think that sometimes it is too easy to hide behind our condition and not take responsability for our lives.
If u like this boy then go for it but be patient, maybe he got embarassed when asked by your friend in which case it is understandable that he denied it all as most of us would when caught unawares.
I was single throughout my teenage years as I didn't have any confidence in myself, a lot of it did have to do with my pcos symptoms but you have to remember that most teens are insecure, it's just part of growing up.
I am now with a wonderful man who loves me for who I am, and our relationship took me completely by surprise as we were really good friends first

. I just wanted to tell you not to worry and that the right man will come along when you least expect it.
