Hmm... I sort of feel the same at times. It has ceased over the years, but it was really strong for, say, the first 18 years of my life (I'm 19 now - I got pregnant by accident and started feeling different about having kids) - I wouldn't call it a delusion - for me, it was/is strong hatred for being female.

A lot of the time I also feel like I'm not a female at all - more like genderqueer (you can look for the term on wikipedia if you don't know what it means) or androgynyous.

You don't have to answer any of this, but you might want to think if you have a traumatic past, abuse or anything?

Also, many people don't really feel like they are a part of either gender. I don't see anything wrong with that.

What I think you have to do is figure out whether the way you feel is wrong for you or not. Maybe through therapy or something you could come to terms with having female reproductive organs.

I won't say much because I don't know what your case is.

Best of luck,
Katie
