My and my really close friend were messing around one night and i "jacked him off" but he moved my hand before it got on it.. but later that night i did it wagain and then he washed his hands and then fingered me.. but after that i went to the bathroom and i was wondering if the cum on my hand.. If there was any could get me pregnant from going to the bathroom.. ive been urinateing a lot since then and this was about a week ago(today is 10-19) could this be a urinary tract infection? Im only 16 and im freaking out this may also be some stress.. please help me!!!
