I'm 14 year old girl and I have never had sex but this clear stuff comes out my vagina?what is it?

Okay, rule of thumb, if it is a vaginal discharge and doesn't have an odour or doesn't have a colour, then it is nothing to worry about. How long have you been menstruating?

I have said this many times here, and if you read to the right of your post you will probably find some of my answers. Our vaginal walls are protected by a Ph balance and unless interrupted by bacteria, say, fingering with dirty nails during foreplay, everything will turn back to a balance that is acceptable. Never douche with anything, this will interrupt that perfect good balance. Okay ? We women are perfectly honed internal micro-organisms of good stuff; if we protect everything and stay clean with good hygiene.
