I am 11 and I have been Masturbating for 2 or 3 years and my semen has now turned white... is this normal?
that means that you've hit puberty and are now producing sperm.
yes that is normal. you are getting older now, so now you are making sperm :-D
I had a clear ejaculation; it has changed. Why?
you weren't making sperm. So your semen was clear. Now that you make sperm, it becomes part of your semen. Sperm is white so that's why your semen is white. It's 100% normal... don't worry about it.
yeppers, sounds like you are producing sperm now
