how long is normal to bleed?

It always astounds me when I hear different women talk and they have no idea how their own bodies work. I can tell by the way you are talking that you don’t know that the hymen (cherry as you called it), is actually on the outside of the vaginal opening, not the inside. Here is all you need to know on this subject but be forewarned it has explicit photos. If you are young, this site is not for you. Write back and I will see if I can find a more appropriate site for you.
And as long as there is no pain or irritation at the site, his fingernails shouldn’t have been a problem. Fingernails are one of the dirtiest places on the human body however and a major breeding place for bacteria. (I am a C.N.A. and one of my specialties was Labor and Delivery wing) The clear liquid could be one of two things. It could be from your excitement and it is just naturally mixed with the blood from the hymen. It could also be the natural clear secretions in the vagina that are there to protect it and clean it - or it could of course be a combination of the two which would make it more copious. If you have more questions, let me know. http://www.the-clitoris.com/f_html/hymen.htm
