Kegel/erection/blood flow question?

I started kegeling recently, probably within the last two weeks and I've run into something that is concerning me. Sometimes when I kegel I feel a strong rush of blood at the shaft of my penis, it feels quite strange, is this normal? Maybe I'm kegeling wrong but I don't think I am based on the things I've read. The reason I'm concerned is because recently I have been having trouble staying erect and I was thinking this might have something to do with it. I no longer get morning wood and don't get erect unless I stimulate myself for a few minutes. I've never had this problem until recently, even a couple of weeks ago I could get very hard and stay hard but now it's a process and I get soft without constant stimulation. I know kegels are supposed to strengthen your erection but is it possible I have done something wrong and weakened mine? I know this is long and I appreciate your responses. I think I'm going to lay off masturbation and kegeling for a while and see if the problem fixes itself but would love to hear from someone who might have gone through this themselves or has some insight on it.
